Other Punctuation

Parentheses 

Parentheses (always used in pairs) allow a writer to provide additional information. The parenthetical material might be a single word, a fragment, or multiple complete sentences. Whatever the material inside the parentheses, it must not be grammatically integral to the surrounding sentence. If it is, the sentence must be recast. This is an easy mistake to avoid. Simply read your sentence without the parenthetical content. If it remains grammatically correct, the parentheses are acceptable; if it doesn’t, the punctuation must be altered.

Apostrophe 

The apostrophe ( ’ ) has three uses: contractions, plurals, and possessives. Contractions Contractions (e.g., let’s, don’t, couldn’t, it’s, she’s) have a bad reputation. Many argue that they have no place at all in formal writing. You should, of course, observe your publisher’s or instructor’s requirements. An absolute avoidance of contractions, however, is likely to make your writing appear stilted and unwelcoming. If you are unsure where to insert the apostrophe when forming a contraction, consult a good dictionary. Avoid two of the most common contraction–apostrophe errors: the contraction of it is is it’s, and the contraction of let us is let’s; without the apostrophe, its is the possessive form of it, and lets is a form of the verb let, as in “to allow or permit.”

Slash 
The slash ( / ), also known as the virgule, has several uses, most of which should be avoided in formal writing. Never use a backslash ( \ ) in place of a slash.

Angle brackets

 In ordinary writing, angle brackets < > are rarely used. In the early days of the internet, angle brackets were sometimes used to enclose an email or web address. This was thought to avoid confusion about whether certain punctuation marks belonged to the address or to the surrounding sentence.

Braces

 Braces { }, also known as curly brackets, are used in various programing languages, certain mathematical expressions, and some musical notation. They should never be used in place of parentheses ( ) or square brackets [ ].
