The basic fact

  The basic fact about the contemporary English comma is that it does not have to mark all the otherwise unmarked junctures of a sentence. There are some that must be marked and some that can but need not be marked. This Chapter will discuss the necessary, unnecessary and the wrong uses of the comma.

The necessary comma

  The comma has to mark only five syntactic junctures:

  • the junctures in a list of single nouns and in a list of noun, adjective and adverb phrases;

  • the juncture of a present-participle phrase and its basic sentence;

  • the juncture of the relative noun phrase and the noun to which it relates;

  • the junctures of the composite sentence;

  • the junctures of single-word adjectives that describe independently.

The necessary comma in a list

  The points between the items of a list must be marked by commas. A list consists of:

  • consecutive nouns and noun phrases;

  • consecutive adjective phrases;

  • consecutive adverb-led phrases. 

The conjunctive `and' takes the place of the comma between the last two items of a list.

Nouns as a list

  Nouns name single items in these sentences. Commas demarcate them:

After the meeting all the chairs, tables, pens and paper they borrowed were returned.

Love, tolerance and charity abound in our society.

Alternate nouns as a list

  The subject raised by the basic sentence of the next sentence is named by the proper noun `Dr Allen Aitken' and by the noun phrase `the director of the local branch of the International Society of Hypnosis'. Two nounal elements that name the same subject constitute a list. Like any items of a list, alternate names must be separated by a comma. A second comma marks the end of the sequence that is the alternate name.

 Dr Allen Aitkenthe director of the local branch of the International Society of Hypnosis, told patients to use strong visual images to help their bodies' defence systems.

When there are several sets of alternately naming sequences, the `listing' practice of demarcating them with commas is again operative. In the next sentence, `an association of doctors using hypnotherapy' is an alternate name for the `International Society of Hypnosis',  just as `the director of the local branch of the International Society of Hypnosis' is an alternate name for `Dr Allen Aitken:'

 Dr Allen Aitkenthe director of the local branch of the International Society of Hypnosisan association of doctors using hypnotherapy, told patients to use strong visual images to help their bodies' defence systems.

Noun phrases as a list

  When objects or abstractions are named by noun phrases each phrase is one item of a list. Each must be demarcated by a comma:

At the station buses for transporting them to the venue, trucks carrying foodstuffs and car-loads of youth-workers had assembled long before the children arrived.

Love of adventure, desire for knowledge and thirst for experience packed our travel plans.

  In the following sentence the content of the copular verb `have long heard' is named by the noun phrases `about World War Two'. This noun-phrase is followed by three adverb-led noun phrases – `from the point of view of veterans', `in books by contemporary historians', `in the writings of journalists' –  that locate the context of the activity `have long heard' occurred. These locative noun phrases, being items of a list, must be demarcated. The first and the second are demarcated with a commas, the second and third with `and':

We have long heard about World War Two from the point of view of veterans, in books by contemporary historians and in the writings of journalists.

Chapter menu

Adjective phrases as a list

  The two phrases: `topped by a little ornamental balustrade' and `its varnish chipped and soiled' describe the noun `writing desk'. They constitute a list of two independent descriptions (though the former is an adjective phrase and the latter a foreshortened sentence acting as an adjective phrase) and must be demarcated from each other.

He noticed a writing desk topped by a little ornamental balustrade, its varnish chipped and soiled.

  The next sentence lists adjective phrases to describe the noun `tendency': `towards big government' and `[towards] big taxing' and `[towards] centralisation of decision-making about our daily lives by faceless boardroom bosses'. Each adjective phrase is an item of a list and must be demarcated:

He has risked his business neck by introducing measures that will reverse the present tendency towards big governmentbig taxingcentralisation of power and  decision-making about our daily lives by faceless boardroom bosses.

Chapter menu

Single-word adjectives and relative-phrases

Some single-word adjectives and relative phrases must be demarcated by commas. They are discussed later, under the heading `Meaning, the comma and the relative phrase'.

Adverb phrases as a list

The next sentence has a `verb + subject' basic sentence. In it the adverb phrases `when we called him', `no matter the day' and `no matter the hour' all describe the time of the subject's act came. As items of a list of descriptions, they must be demarcated by commas:

The doctor came when we called him, no matter the day, no matter the hour.

Chapter menu

The necessary comma and the present-participle phrase

  The present-participle phrase must be demarcated with a comma from the basic sentence when it attaches to its verb by describing it. (In this sentence the present participle `giving' leads the noun phrase `a taste of the verbal skills' to describes the manner of subject's activity `enable', of which the content has already been named by the noun phrase `to listen to a Coleridge conversation'):

Coleridge's private notebooks enable us to listen to a Coleridge conversationgiving a taste of the verbal skills with which he so often bedazzled his listeners.

Chapter menu

Necessary comma and the composite sentence

  In a composite sentence (see the Chapter `The Composite Sentence') commas demarcate: 

(i) the listed sentences and the `result' sentence:

He is dumbfounded, he is dazed, he doesn't know what to say, so I feel free to laugh.

(ii) the foreshortened sentence:

Infatuated, the boy gave her his favourite teddy bear, which was an act of generosity he still regrets.

The opposition, knowing the popularity of the government's attitude to the war, was reluctant to criticise the military high command.

(iii) The attributing sentence: 

`That you are entitled to the view is beyond doubt', he smiled.

The dining room is, he hastened to inform us, for  the use of members only.

(iv) The direct address (vocative) noun or noun phrase:

You've burnt the meat, Chef.

Year 12 students, please do your homework before you go out.

EXERCISE 13 is appropriate here.

Meanings that make the comma either obligatory or wrong

  The comma can make meaning for reason alone of its presence or absence in a sentence. Its use in specific circumstances  is therefore either obligatory or wrong, depending on the meaning the writer wants to make. 

The comma, meaning and the relative phrases

  It is the comma that determines the meaning that relative phrases make. In this sentence the meaning is: All things that are `electricity-distributing companies' are `things that lost money':

Electricity-distributing companies, which lost money because of the blackouts, want compensation.
All electricity-distributing companies lost money

Meaning changes when the comma is removed from this sentence. It becomes: `Some things that are "electricity-distributing companies" are "some things that lost money" ':

Electricity-distributing companies that lost money because of the blackouts want compensation.
Only some electricity-distributing companies lost money.

Comma-determined meanings of this kind occur in the next sentences:

Mothers, who have a well developed sense of the ridiculous, are easy going.
All mothers have a well developed sense of the ridiculous and they are easy going.

Mothers who have a well developed sense of the ridiculous are easy going.
Only those mothers who have a well developed sense of the ridiculous are easy going.

The last scene, in which  the reconciled family sang to mother's piano accompaniment, was altogether too sentimental.
The scene was the last scene and the family sang in it.

The last scene in which [or where] the reconciled family sang to mother's piano accompaniment was altogether too sentimental.
The scene was the last of the scenes in which the family sang (but not the last scene of the play.

My son, Andrew, is a law student.
My son, whose name is Andrew, is a law student.
I have one son and his name is Andrew. (A reader comments.)

My son Andrew is a Law student.
My son whose name is Andrew is a law student.
I have several sons and one is named Andrew.

The author, whom you know, is speaking tonight.
You know the author and she is speaking tonight.

The author whom you know is speaking tonight.
The author whom you know (not the author whom you do not know) is speaking tonight.

The comma, meaning and -ly words

  Words such as `hopefully', `obviously', `clearly' can be used either as adverbs or as the foreshortened sentence that splices to make a composite sentence. The comma determines that they are foreshortened sentences and distinguishes their meaning from that of the adverbs:

adverbs

foreshortened sentences


They have come home hopefully.
They came home filled with hope.


They have come home, hopefully.
It is hoped that they have come home.


The men did not hurt him obviously.
The way the men hurt him was not obvious.


The men did not hurt him, obviously.
It is obvious that the men did not hurt him.


The old man cannot see clearly.
The old man's vision is not clear.


The old man cannot see, clearly.
It is clear that the old man cannot see.

  Composite-sentence wordings are sometimes identical with compound-sentence wordings. In the next sentences commas determine that they are composite sentences and distinguishes their meanings from those of the compound sentences:

composite sentence

compound sentences


I didn't buy it, because it was expensive.
I didn't buy it. It was expensive


I didn't buy it because it was expensive.
I bought it for some reason other than that it was expensive.


People held their noses. But, while the stench was pervasive, it was not dangerous.
The pervasive stench was not dangerous.


People held their noses. But while the stench was pervasive it was not dangerous.
The stench was not dangerous during the time that it was pervasive.

Chapter menu

Wrongly used commas

  The comma, like any other internal sentence marker, can be used only at a syntactic juncture in the sentence. There is no syntactic juncture in any sequence that is one syntactic unit. So there is no syntactic juncture in:

  • the basic sentence;

  • the foreshortened sentence;

  • the attributing sentence;

  • phrases (noun, adjective, predicate adjective, adverb, participle, relative);

  • between a noun (or noun phrase) and the adjective (or adjective phrase) that describes it.

If a comma is placed at any point in the sentence that is not a syntactic juncture, then that comma is wrongly used. The following wrong uses of the comma are common. Common to all of them is the failure to realise that they mark a point that is not a syntactic juncture.

The comma that disrupts a basic sentence

  There is no juncture between a subject and its object or complement. There cannot be. `Subject and object/complement' is the syntactic unit `basic sentence'. Failure to recognise the subject can lead writers into the mistake of disrupting a basic sentence:

wrongly used comma
That he knows it to be completely illegal in this country, is not going to stop him from doing it.

The noun phrase `That he knows it to be completely illegal in this country' names the subject every bit as much as if it were the one-word name `John'. Nobody would write `John, is not going to stop him', because everybody knows that there is no syntactic juncture in the text of a basic sentence. This holds true also when the subject is named by a noun phrase. The sentence should have been written thus:

That he knows it to be completely illegal in this country is not going to stop him from doing it.

  The same mistake occurs in the following sentence. The subject is named by the noun phrase This travelling circus of amateur athletes.

wrongly used comma
This travelling circus of amateur athletes, is ludicrous beyond anyone's imagination.

It should have been written without a comma: 

This travelling circus of amateur athletes is ludicrous beyond anyone's imagination.

  Long sentences often prompt people to drop in a comma for `appearance' sake. This writer's comma was probably one of those jobs. It did only harm, as such `drops' are wont to do. It disrupted his basic sentence:

wrongly used comma
The hope that Australians would become as enthusiastic about science as they are about sport, prompted calls for a national innovation institute.

The sentence should be without that comma:

The hope that Australians would become as enthusiastic about science as they are about sport prompted calls for a national innovation institute.

  Just as the comma must not disrupt the basic sentence at its subject stage, so it must not disrupt it at its object/complement stage. The comma in this sentence disrupted it by demarcating its adverb complement:

wrongly used comma (the first one)
He came, later than expected, keen to surprise us.

There should be no comma in the basic sentence:

He came later than expected, keen to surprise us.

Nobody would even contemplate a comma after `came' in the foregoing sentence if `later' were the only word of its adverb complement. That the complement is the adverb phrase `later than expected' is no reason for thinking the comma admissible.

Chapter menu

The comma that disrupts a noun phrase

This writer demarcated the adjectival element of his noun phrase and thereby disrupted it:

wrongly used comma
The strike, over the new nurses' pay award, entered its second day today but hospitals reported minimal disruption to services.

The phrase `over the nurses' pay award' should not have been demarcated. It is part of the noun phrase that names the subject:

The strike over the new nurses' pay award entered its second day today but hospitals reported minimal disruption to services.

  In the next sentence the disrupted noun phrase is the very one that specifies the content of the subject's act `said'. That disruption hampers the specification:

wrongly used comma
Mr White said that it is safer for residents to make a bushfire plan ahead of time, by deciding to stay or leave in the event of a fire.

The sentence should have been written without this comma:

Mr White said that it is safer for residents to make a bushfire plan ahead of time by deciding to stay or leave in the event of a fire.

The comma that disrupts a foreshortened sentence

  Some writers become nervous when their descriptive sequences get to be longish, and they scratch in a comma with a view to tethering it. The comma, however, does not tether. It disrupts, making the reader lose track of what is being described. This writer's sentence is an example of a disrupting comma in an adjective phrase-cum- foreshortened sentence

wrongly used comma
Well located, in an elevated position, on a wide block by the river, the house features ornate ceilings and leadlight windows.

The foreshortened sentence `Well located in an elevated position on a wide block by the river' is the adjective that describes the subject `the house' of the independent sentence with which it splices. There is no role for commas in it:

Well located in an elevated position on a wide block by the river, the house features ornate ceilings and leadlight windows.

EXERCISE 17 is appropriate here.

The optional comma

  Writers sometimes place commas at syntactic junctures where they are not necessary. They do this because they like to, or in order to achieve certain stylistic effects. So long as they are at syntactic junctures, these placements are not wrong uses of the comma. But it is just as well to remember that contemporary publication favours a lightly punctuated text. In the light of this it is best to avoid using all but the necessary commas.

The commas with a compounding operator

  A celebrated stylist had this to say about commas used with compounding operators:

You are very free with yr commas. I always reduce them to a minimum & use an `and' or an `or' as a substitute, not as an addition. Let us argue it out.
Winston Churchill 1922, to Edward Marsh, quoted by David Irving

There certainly is a good case against using commas in a compound sentence. In them the compounding operators mark the syntactic junctures of a sentence. They makes the comma superfluous:

He went away despite our advice.

We did not approach him because we knew he was promised to a rival firm.

Although he is still under twenty he is a self-made millionaire.

While it is true that he committed this crime it is also true that he is not a habitual criminal.

  A comma with the compounding operator in the spliced `result' sentence of a composite sentence is another matter. It has its list to plead: If the comma does not mark the final item of that list, then the reader, expecting another item, trips on the unexpected structure of the `result' sentence:

A great deal of modernism is absurd, much of what passes for its theory is intellectual butterfly-catching, most of its proponents are lightweights, yet Jones is awe-struck by its wisdom.

  The longish compounding-operator regulated sentence has its length to plead a need for the comma. Such a sentence might even have a coincidence of the same or similar words that make a comma essential:

While shards are being talked up by their architect promoters as the features that make skylines pleasingly a-symmetrical, a-symmetry of skylines features little in the thoughts of developers who also talk them up.

Chapter menu

Commas when an adverb phrase embeds the basic sentence

Adverb-led phrases can but need not be demarcated from the basic sentence of which they are not an integral part. Adverb phrases in these sentences are not parts of the basic sentences:

This painting is before anything else a study of the painter's soul.

This painting is, before anything else, a study of the painter's soul.

In her majestic account of the first forty years of  Matisse's  life Martha Harris shows how wrong we were about the artist.

In her majestic account of the first forty years of  Matisse's  life, Martha Harris shows how wrong we were about the artist.

Rights and the expendable comma

  The writer who likes to use commas at all available syntactic junctures will argue that they help the reader through a sentence. That writer has to be allowed to exercise his taste in the matter. But the one who inclines to using his commas sparingly must also be allowed his preference. Should anyone on his behalf insert commas he chose to do without, he is fully entitled to object.

  The striking-out of an `unnecessary' comma can earn the incautious editor some well-deserved castigation. The one who denuded this sentence of its commas, on the ground that they are separating a predicate-adjective phrase from the subject it describes, had it pointed out, to her embarrassment, that the commas are properly demarcating a foreshortened sentence:

Poetry springs, unbidden and perfectly formed, directly from his experiences.

Chapter menu

The parenthetical comma

  Writers often demarcate a sequence that is both an adjective and a foreshortened sentence. They do this in order to emphasise it. In this sentence the writer wanted the sequence `known both as Alan Ward and Thomas Jeffreys' to do more than just describe the subject `This elusive man': He wanted it to make the point that a man is known both as `Alan Ward' and as `Thomas Jeffreys'. That point is an `aside', or a parenthetical departure, from the point his sentence is making. No editor is licensed to meddle with his intention by deleting the parenthetical commas:

This man, known both as Alan Ward and Thomas Jeffreys, managed to evade the most rigorous police hunt ever launched in this State.

On the other hand, some writers are such zealous employers of the comma that they become irritating:

The pact signed, and, just for formality's sake, also sealed, our host reached, ceremoniously, for the champagne bottle.

There must be sympathy for the editor who disallows this accumulation of gratuitous commas:

The pact signed and just for formality's sake also sealed, our host reached ceremoniously for the champagne bottle.

Chapter menu

The comma does not rescue bad construction

  There is no point in trying to `doctor' a badly constructed sentence with a comma. The comma simply is not up to the job. The writer of this sentence inserted a comma in the hope of healing its ambiguity:

defective sentence
In the light of the fact that he is very well qualified, we will reconsider his retrenchment.

There are two statement here:

(i) When we reconsider his retrenchment we will do so in the light of the fact that he is very well qualified.

(ii) Because he is very well qualified we will reconsider his retrenchment.

This writer probably misunderstood the sequence `In the light of the fact that he is very well qualified' to mean `because'. Apparently uncomfortable with his composition, he hoped to improve it by scratching in a comma. However, a comma will not improve bad construction, nor correct the misuse of an expressions.

The comma and single-word adjectives

  When adjectives describe as sequential single words (not as phrases) they perform as sets of independent descriptions or as sets of interdependent descriptions.

Adjective as independent descriptions

  Independent adjectives display the discrete facets of the noun they are describing. They list descriptions. As items of a list these descriptions are necessarily separated by commas.

That smelly, dirty, ragged coat is still his favourite one.

Adjective as interdependent descriptions

  Interdependent adjectives describe a noun by defining it. They are part of the naming sequence `noun phrase'. They must not be demarcated by commas precisely because they are parts of a noun phrase. In the following sentence interdependent adjectives (`little' and `old)' are part of a noun phrase that includes the noun itself (`the lady')  and a relative-adjective phrase  (`who lives next door'). This noun phrase, `the little old lady who lives next door', is also an alternate name for `Kate':

Kate, the little old lady who lives next door, gave us a cake.

Chapter menu

The different `doings' of independent and interdependent adjectives

  That independent and interdependent adjectives `do' different things becomes evident in their distinctive ways of having either:

(i) descriptive copula-sentence templates of meaning (the independent adjectives)

or

(ii) definitive copula-sentence templates of meaning (the interdependent adjectives).


The descriptive copula-sentence templates of independent adjectives

  The independent-adjective sequence of each of the following sentences has the meaning-template form of the copula sentence in which the subject is described by predicate adjectives. Several predicate adjectives constitute a list of descriptions. As items of a list they must be demarcated by commas:

According to her biographer, Elizabeth David was an elegant, witty, charming minor monster.
[the] elegant, [the] witty, [the] charming, [the] minor monster Elizabeth David.

subject

copula

predicate-adjective

The minor monster Elizabeth David

was

elegant and witty and charming.

 

Lady Caroline Lamb said that Lord Byron was mad, bad and dangerous to know.
[the] mad, [the] bad, [the] dangerous-to-know Lord Byron.

subject

copula

predicate adjective

Lord Byron

was

mad and bad and dangerous to know.

 

The exhibition presented an interesting and well-chosen selection of portraits.
[the] interesting and [the] well-chosen selection.

subject

copula

predicate adjective

The selection of portraits

was

interesting and well-chosen.

 

The definitive copula-sentence templates of interdependent adjectives

  The interdependent-adjective sequence of each of the following sentences has the form of the copula sentence of which the predicate noun defines the subject:

Pompous military regulations prevented wives from accompanying their husbands.
`
Some regulations' = `pompous military regulations'

subject

copula

predicate noun

[Some] regulations

are

pompous military regulations.

 

Before Pushkin there were a few minor poets in Russia.
`Poets' in Russia = `the few minor poets'

subject

copula

predicate-adjective

`Poets in Russia'

were

the few minor poets.

 

Diego Rivera rapidly became the most famous Mexican painter.
`The painter' = `the most famous Mexican painter'

subject

copula

predicate-adjective

The painter

is

the most famous Mexican painter.

Contracted interdependent-adjectives sequences

  Sentences often look as if an adjective that describes independently has conjoined with a sequence of interdependent adjectives. But such sentences are instances less of the conjoining than of the contracting of two sequences of interdependent adjectives. The next sentence contracts two depictions of `a Tokyo artist'. The comma between `quiet' and `self-effacing' indicates the duality of the depiction. Inasmuch as this is a list of two depictions, the comma correctly separates them:

This quiet, self-effacing Tokyo artist has languished in captivity for years.

(i) This quiet Tokyo artist has languished in captivity. 
(ii) This self-effacing Tokyo artist has languished in captivity for years.

The next sentences contracts three depictions of `ancestral home'.

From the formality of his large, opulent, dignified ancestral home, he pads out in bare feet to greet the visitor.

(i) From the formality of his large ancestral home, he pads out in bare feet to greet the visitor.
(ii) From the formality of his opulent ancestral home, he pads out in bare feet to greet the visitor.
(iii) From the formality of his dignified ancestral home, he pads out in bare feet to greet the visitor.

The two depictions of `game sauce 'in the next sentence have contracted the separate descriptions `aged' and `highly spiced'. Hence the comma between them:

His famous aged, highly spiced game sauce tempted us.

(i) His famous highly spiced game sauce tempted us.
(ii) His famous aged game sauce tempted us.

Independent and interdependent adjective sequences and the `and' test

  `Are they describing or defining?' is the criterion for distinguishing the independent-adjective sequence from the interdependent one. If they are describing, then `and' is capable of intervening. If they are defining then `and' cannot intervene. The following adjectives, for instance, are not saying of  `a bonnet' that is `a chancellor's and is `floppy' and is `velvet' and is `doctoral':

One inclines to advise him to stick to beer and boating and to warn him that he might look strange under a chancellor's floppy velvet doctoral bonnet.

They are saying that `the bonnet' is ( = ) `a chancellor's floppy velvet doctoral bonnet'. They are therefore defining `bonnet'. Applied to this sentence, the `and' test failed, revealing the definitive, interdependent character of its adjective sequence. Being definitive, that sequence is part of a naming sequence and is therefore a set of interdependent adjectives that must not be demarcated by commas.

  The next sentence will sustain the `and' test:

 There was a great spirit about the Club, quite unlike a nasty, stifling nuclear family's.

It is saying of the nuclear family's spirit that it is `nasty' and `stifling'. Sustaining the `and'  test, these adjectives reveal themselves to be independent descriptions that must be demarcated by a comma.

A caution

  The failure to distinguish independent and interdependent adjective sequences is the most common abuse of comma in the daily press. Writers should be on their guard when they read newspapers.
