The most common mistake people tend to make while writing is in the use of Punctuation. Wrong punctuation can damage the flow of ideas and change meaning, but properly used punctuation not only helps readers understand your meaning but also makes them engrossed in your writing. The following discussion is about some of the frequently misused punctuation marks and what actually their correct application should be.

Use of Apostrophe - Use an apostrophe to show possession, but never put apostrophe in case of possessive pronouns. Always remember that when the word "it's" is used, it is actually for the contraction for the two words: "it has" or "it is". On the other hand, "its" is a possessive pronoun, and the word being already possessive should not contain an apostrophe in it.

Example

It's the same thing happening over and over again.
(Contraction of It and is: It is the same thing happening over and over again).

Wrong: That car is your's.

Right: That car is yours.

Note: Rewriting is sometimes the solution for an awkward possessive.

Awkward: A friend of mine's cap.

Better: A friend's cap (or the cap of a friend of mine).

To show possession in the case of singular nouns, add 's, and for plural words that end in s, add only an apostrophe. Don't forget to put 's with plural words not ending in s.

Example

Singular: nurse's uniform

Plural: nurses' uniforms (plural word ending in s)

Plural: children's uniforms (plural word not ending in s)
