Punctuation Marks are used to make the sense more clear.

A Period (.) is used at the end of a sentence, and after an abbreviation; as,

James was quite sick. Dr. Jones was called to see him.

An Interrogation Mark (?) is used at the end of a question; as,

Where is John going?

An Exclamation Mark (!) is used after words or sentences expressing some strong feeling; as,

Alas, my noble boy! that thou shouldst die!

The Comma (,), Semicolon (;), and Colon (:) are used to separate the parts of a sentence.

The Hyphen (-) is used to join the parts of a compound word; as, text-book: it is also used at the end of a line in print or script, when a word is divided; as in the word "sentence," near the bottom of page 9. [Transcriber's note: Hyphenation not shown in this HTML edition.]
