An apostrophe is used in contracted forms such as the following: can't, won't, didn't, he's, she'd, they're, let's. However, these contractions are not usually used in formal academic writing.
An apostrophe is also used to signal possession or ownership. Add -'s to signal possession. If the noun is a plural form ending in -s, add only an apostrophe.
her son's room (one son)
her daughters' room (two daughters, one room)
the teachers' reports (more than one teacher: plural -s)
the children's books (more than one child, but no -s for plural form)
However, apostrophes are not used with the names of buildings, objects, or pieces of furniture (the hotel pool, the car door, the table leg) or with possessive adjectives (its, yours, hers). The form "it's" is a contraction for it is or it has.
