I thought this was a given, but clearly I was wrong. Verbs don’t need an ‘s tacked on to their rear end. He knows, NOT know’s. He doesn’t know’s a damn thing. (And clearly you don’t either if you wrote it!). I know, you know, he/she/it knows. No magic, no math. Just an ‘s’ people, just an ‘s’. The apostrophe is not invited to this party. And guess what? He doesn’t want to be there either!
The apostrophe indicates ownership. Jack’s car – the car Jack owns, or the car belonging to Jack. Verbs can’t own things…
Apostrophes are also used for contractions (not the kind women have during childbirth, but if that helps you remember, go for it!). Therefore, can’t is the contracted form of cannot. See the lil apostrophe in there? Expand the contraction.
