# U.S. Government Printing Office Style Manual/Punctuation

Punctuation is used to clarify the meaning of written or printed language. Well-planned word order requires a minimum of punctuation. The trend toward less punctuation calls for skillful phrasing to avoid ambiguity and to ensure exact interpretation. The GPO Style Manual can only offer general rules of text treatment. A rigid design or pattern of punctuation cannot be laid down, except in broad terms. The adopted style, however, must be consistent and based on sentence structure.
The general principles governing the use of punctuation are: If it does not clarify the text it should be omitted; and, in the choice and placing of punctuation marks, the sole aim should be to bring out more clearly the author's thought. Punctuation should aid reading and prevent misreading.
The possessive case of a singular or plural noun not ending in s is formed by adding an apostrophe and s. The possessive case of a singular or plural noun ending in s or with an s sound is formed by adding an apostrophe only. Some irregular plurals require both an apostrophe and an s. (For possessives of italicized nouns, see rule 11.6.)

Three asterisks (preferred form) or three periods, separated by en spaces, are used to denote an ellipsis within a sentence, at the beginning or end of a sentence, or in two or more consecutive sentences. To achieve faithful reproduction of excerpt material, editors using period ellipses should indicate placement of the terminal period in relation to an ellipsis at the end of a sentence. Note, in the following examples, the additional spacing necessary to clearly define commas and the terminal period when period ellipses are employed.
    The Senate having tried Andrew Johnson, President of the United States, upon articles of impeachment exhibited against him by the House of Representatives, and two-thirds of the Senators present not having found him guilty of the charges contained in the second, third, and eleventh articles of impeachment, it is therefore

    The Senate having tried Andrew Johnson * * * upon articles of impeachment * * * and two-thirds of the Senators present not having found him guilty of the charges * * *, it is therefore
    Ordered and adjudged. That the said Andrew Johnson, President of the United States be * * * acquitted of the charges * * *.
    The Senate having tried Andrew Johnson … upon articles of impeachment … and two-thirds of the Senators present not having found him guilty of the charges …, it is therefore
    Ordered and adjudged. That the said Andrew Johnson, President of the United States be … acquitted of the charges.…
Ellipses are not overrun alone at the end of a paragraph.
When periods are not specifically requested for ellipses in copy that has both periods and asterisks, asterisks will be used.
A line of asterisks indicates an omission of one or more entire paragraphs. In 26½-pica or wider measure, a line of "stars" means seven asterisks indented 2 ems at each end of the line, with the remaining space divided evenly between the asterisks. In measures less than 26½ picas, five asterisks are used. Quotation marks are not used on a line of asterisks in quoted matter. Where an ellipsis line ends a complete quotation, no closing quote is used.
Indented matter in 26½-pica or wider measure also requires a seven-asterisk line to indicate the omission of one or more entire paragraphs.
If an omission occurs in the last part of a paragraph immediately before a line of asterisks, three asterisks are used, in addition to the line of asterisks, to indicate such an omission.
Equalize spacing above and below an ellipsis line.
The exclamation point is used to mark surprise, incredulity, admiration, appeal, or other strong emotion which may be expressed even in a declarative or interrogative sentence.
    Who shouted, "All aboard!" [Note omission of question mark.]
    "Great!" he shouted. [Note omission of comma.]

    Mayday! Mayday!
In direct address, either to a person or a personified object, O is used without an exclamation point, or other punctuation; but if strong feeling is expressed, an exclamation point is placed at the end of the statement.
    O my friend, let us consider this subject impartially.
    O Lord, save Thy people!
In exclamations without direct address or appeal, oh is used instead of O, and the exclamation point is omitted.
    Oh, but the gentleman is mistaken.
    Oh dear; the time is so short.
The hyphen (a punctuation mark, not an element in the spelling of words) is used—
To connect the elements of certain compound words. (See Chapter 6 "Compounding Rules.")
To indicate continuation of a word divided at the end of a line. (See Word Division, supplement to the Style Manual.)
