Punctuation

The apostrophe has two main uses in English. It shows where letters have been left out in contractions (it's, don't) and it shows ownership or possession (the dog's lead, the students' books).

Commas are used to separate items in a list, after introductory phrases, before coordinating conjunctions in compound sentences, and around non-defining relative clauses. Knowing when to use commas makes writing clearer.
