Punctuation
i llustrating the idea of guilt mentioned in the first part (that preceding the colon).
A similar example is found in the same author:
Fielding was a blank, frank atheist, but he respected every opinion his friend held: to do this is essential to friendship. The part preceding the colon in this case is itself a compound sentence (in a somewhat loose application of the term); this, however, is irrelevant for the fact that the colon is a signal of a compound sentence, in so far as there is an independent clause on either side of it.
The function of the colon is somewhat more complicated because it is occasionally used to introduce direct speech. It is well known, however, that this use of the colon is much less characteristic of English than of Russian: in English direct speech is often preceded by a comma, especially if it does not begin a new paragraph.
The grammatical significance of the comma is much harder to define. Its uses are so varied that it appears to be practically impossible to give it a general characteristic: it may mark the end of a main clause, or of a subordinate clause, or it may stand between homogeneous members (whether subjects,
predicates, predicatives, objects, adverbial modifiers, or attributes), or it may also mark off an apposition, a direct address, etc. The only thing that may perhaps be said about the function of the comma in general is, that it marks some kind of syntactical division. It will perhaps be best to illustrate this by pointing out contexts in which a comma would not be possible. These are:
(1) The group of attribute and head word (by attribute is meant one that is not loose). No comma would for instance
be possible after the word one, or after
two, or after
distinct in the following sentence:
At one period two distinct tombs containing Esmiss Esmoor's remains were reported. (FORSTER) (2) The group of subject and predicate. Thus, no comma would be possible after the word
Fielding in the sentence,
Fielding said no more (Idem), or after the word
Weeks, or after
eyes, or
Philip, or
American in the sentence
Weeks spoke seriously, but his gray eyes twinkled a little at the end of his long speech, and Philip flushed when he saw that the American was making fun of him. (MAUGHAM) Commas are also impossible in certain other groups, as between a preposition and a noun. The essential point is, that a comma does mark some kind of grammatical division, at least that between homogeneous parts of a sentence or that between a loose secondary part and the rest of the sentence. The more exact function of a comma in every given case can only be made out by considering its syntactical surroundings.
Such, then, would appear to be the grammatical functions of punctuation marks. They might also be shown by a very simple experiment: dropping all punctuation marks from a certain passage in a text and finding out what points in the grammatical structure
The Comma 345
o f the passage are lost or at least obscured by this omission. This would reveal the exact value of punctuation from the grammatical viewpoint.

The function of inverted commas, or quotation marks (" "), stands somewhat apart from that of other punctuation marks. From the grammatical viewpoint inverted commas appear to have no significance.
1 A similar investigation might be made about the grammatical value of intonation. But this would require experimental
study of English pronunciation, which lies beyond the scope of this book. Some main points concerning the grammatical value of intonation are to be found in books on phonetics.
