Dr Grammar | Apostrophes
We use apostrophes (‘) for 2 main reasons:
1. missing letters
To show that letters are missing, e.g isn’t = is not, doesn’t = does not, I’d = I would / I had ,it’s = it is
To show possession. Note the position of the apostrophe is determined by the noun:
singular noun + ‘s my son’s IPad
plural noun + s’ my parents’ IPad
irregular plural + ‘s women’s clothing
You will sometimes see an apostrophe added to a singular noun ending ‘s, especially classical names e.g Jesus’ disciples, but Jesus’s disciples is also correct. Apostrophe + s is more common e.g. Lar’s dog bit me
We do not use apostrophes (‘) with possessive determiners: my, your, his, her its, our and their, or pronouns. e.g I, she, they, mine, hers, theirs etc.
You will see apostrophes used in other situations, e.g the 1990’s but you can also write 1990s, this is a question of style and usage.
