Explanation:

The apostrophe (') is a punctuation mark used in English language to form possessive nouns, mark the omission of one or more letters and to indicate the plurals of letters in lowercases.

For example, forming a possessive noun; add an Apostrophe (') with the letter "s" i.e ('s) to nouns that don't end with "s" sound. Also, you can add only an Apostrophe (') without the letter "s" to nouns that ends with "s" sound.

For instance, the financial planner’s e-mail address was listed on his website, the writer's pen, the cat's eyeballs etc.

To indicate the omission of a letter (contraction), such as isn't, don't they're, I've, you're, doesn't, you've, they'd etc.
