Punctuation marks are symbols that indicate the structure and organization of written language, as well as intonation and pauses to be observed when reading aloud.

In written English, punctuation is vital to disambiguate the meaning of sentences. For example, "woman, without her man, is nothing" (emphasizing the importance of men) and "woman: without her, man is nothing" (emphasizing the importance of women) have greatly different meanings, as do "eats shoots and leaves" (to mean "consumes plant growths") and "eats, shoots and leaves" (to mean "eats firstly, fires a weapon secondly, and leaves the scene thirdly")

     The full stop (.), also called the period, presents few problems. It is chiefly used to mark the end of a sentence expressing a statement.

A question mark (?) is placed at the end of a sentence which is a direct question. 

The exclamation mark (!), known informally as a bang or a shriek, is used at the end of a sentence or a short phrase which expresses very strong feeling.

The comma (,) is very frequently used and very frequently used wrongly. In fact, the rules for using commas are really rather simple, though complicated by the fact that the comma has four distinct uses.

The colon (:) seems to bewilder many people, though it's really rather easy to use correctly, since it has only one major use. But first please note the following: the colon is never preceded by a white space.

The semicolon (;) has only one major use. It is used to join two complete sentences into a single written sentence.

The hyphen (-) is the small bar found on every keyboard. It has several related uses; in every case, it is used to show that what it is attached to does not make up a complete word by itself. The hyphen must never be used with white spaces at both ends, though in some uses it may have a white space at one end.

The use of quotation marks, also called inverted commas, is very slightly complicated by the fact that there are two types: single quotes (` ') and double quotes (" "). As a general rule, British usage has in the past usually preferred single quotes for ordinary use, but double quotes are now increasingly common; American usage has always preferred double quotes.
