End of the Sentence 337
end of a sentence and to its Communication type.
These two functions, though essentially different, are performed by punctuation marks simultaneously.
The punctuation marks performing these functions are, the full stop (.), the question mark (?), and the exclamation mark (!).
The full stop may, in general, be said to be a signal of the end of a sentence, though its use as a sign of abbreviation (in
such expressions as а. т., р. т., В. С., A. D., etc.) shows that its sentence-ending function is not necessarily the only one. However, with this reservation the function of the full stop as a signal of sentence end may be said to be almost certain.

The other function of the full stop refers to the communication character of the sentence. Namely, a full stop shows that the sentence is not interrogative and not exclamatory. That is the only conclusion in this way that can be drawn from it. The question whether the sentence
is declarative or imperative cannot be settled by the presence of a full stop at the end. Imperative sentences with a full stop at the end are quite possible, though not exactly frequent. Here are a few examples:
Oh, just look at the collar, and those sleeves and those pockets. (DREISER)
Don't go acting like this. (Idem) The utmost that can be said in this respect is that it is much more likely for a sentence ending with a full stop to be a declarative than an imperative sentence.
The other two punctuation marks which can signal the end of a sentence are the question mark and the exclamation mark. This function of theirs may be said to be almost certain. We are, however, bound to say "almost", because we must take into account some special cases, mainly in direct speech, where there may be a question
mark or an exclamation mark, though the sentence including direct speech may run on after that, as in the following examples:
"Renegade!" said Mr Blythe. (GALSWORTHY)
"Why can one always tell an Englishman?" said John. (Idem) Of course there are two things to be distinguished here. The sentence
"Renegade!" as pronounced by Mr Blythe is certainly finished where the exclamation mark stands, and so is the sentence
"Why can one always tell an Englishman?" as
pronounced by John, at the point where the interrogation mark stands. But the sentences
"Renegade!" said Mr Blythe and
"Why can one always tell an Englishman?" said
1 It should be noted, too, that in recent times the use of the full stop in abbreviations tends to be restricted. For instance, nowadays no full stop is used if the last letter of an abbreviation is the last letter of the word, as in
Mr, Mrs. There is also a tendency to drop the full stop in such abbreviations as
n (for noun),
v (for verb)
in dictionaries, etc. This makes the function of the full stop to mark the sentence end more certain.
