Хм, что-то я запутался

let vs lets vs let's

they are all words

"let" we all know how to use it Agreed!? thats the easy part

"Let" me borrow a pen.
"Let" me leave this place.
"Let" it go please.
I would like it if she'd "let" me go.

Got it?

"Lets" is to show action referring only to one thing.

My brother "lets" me hold his car.
She always "lets" me win.
My mother always "lets" my sister get away with things.

"Let's" is a contraction word meaning let us. So, if let us doesn't fit then neither does "let's"

"Let's" go to the mall. "Let us" go to the mall
My brother "let's" me borrow his car. My bother "let us" me borrow the car. See how this is obviously wrong.
