## I. Introductory

This handbook summarizes the essentials of plain English style. It focuses on the rules of usage and principles of composition most often broken, offering a compact alternative to exhaustive manuals. Master the guidance here, then look to the best authors for finer points of style.

## II. Elementary Rules Of Usage

### Rule 1. Form the possessive singular of nouns by adding 's

Follow this rule whatever the final consonant. Thus write,

Charles's friend

Burns's poems

the witch's malice

This is the usage of the United States Government Printing Office and of the Oxford University Press.

Exceptions are the possessive of ancient proper names in *-es* and *-is*, the possessive *Jesus'*, and such forms as *for conscience' sake*, *for righteousness' sake*. But such forms as *Achilles' heel*, *Moses' laws*, *Isis' temple* are commonly replaced by

the heel of Achilles

the laws of Moses

the temple of Isis

The pronominal possessives *hers*, *its*, *theirs*, *yours*, and *oneself* have no apostrophe.

### Rule 2. In a series of three or more terms with a single conjunction, use a comma after each term except the last

Thus write,

red, white, and blue

gold, silver, or copper

He opened the letter, read it, and made a note of its contents.

This is also the usage of the Government Printing Office and of the Oxford University Press.

In the names of business firms the last comma is omitted, as,

Brown, Shipley & Co.

### Rule 3. Enclose parenthetic expressions between commas

The best way to see a country, unless you are pressed for time, is to travel on foot.

This rule is difficult to apply; it is frequently hard to decide whether a single word, such as *however*, or a brief phrase, is or is not parenthetic. If the interruption to the flow of the sentence is but slight, the writer may safely omit the commas. But whether the interruption be slight or considerable, he must never insert one comma and omit the other. Such punctuation as

Marjorie's husband, Colonel Nelson paid us a visit yesterday,

or

My brother you will be pleased to hear, is now in perfect health,

is indefensible.

If a parenthetic expression is preceded by a conjunction, place the first comma before the conjunction, not after it.

He saw us coming, and unaware that we had learned of his treachery, greeted us with a smile.

Always to be regarded as parenthetic and to be enclosed between commas (or, at the end of the sentence, between comma and period) are the following:

\(1\) the year, when forming part of a date, and the day of the month, when following the day of the week:

February to July, 1916.

April 6, 1917.

Monday, November 11, 1918.

\(2\) the abbreviations *etc.* and *jr.*

\(3\) non-restrictive relative clauses, that is, those which do not serve to identify or define the antecedent noun, and similar clauses introduced by conjunctions indicating time or place.

The audience, which had at first been indifferent, became more and more interested.

In this sentence the clause introduced by *which* does not serve to tell which of several possible audiences is meant; what audience is in question is supposed to be already known. The clause adds, parenthetically, a statement supplementing that in the main clause. The sentence is virtually a combination of two statements which might have been made independently:

The audience had at first been indifferent. It became more and more interested.

Compare the restrictive relative clause, not set off by commas, in the sentence,

The candidate who best meets these requirements will obtain the place.

Here the clause introduced by *who* does serve to tell which of several possible candida
