Other forms: commas

A comma is the small curved mark that gives a sentence a tiny pause. Put a comma there, a missing comma, the Oxford comma.

It separates items in a list and marks off clauses, and misplacing one changes the meaning — which is why the difference between let's eat, Grandma and let's eat Grandma is the standard joke. The Oxford comma before the final and is optional and argued about endlessly. A comma splice joins two sentences with a comma where a full stop or a semicolon belongs.
