Toward/towards is a preposition, not a verb.
They mean the same, but as an American, I'm more inclined to use toward.

The word toward
I know when the subject is singular the verb is singular too. When the subject is plural the verb is plural too. My question is when it come to the word toward, is it toward or towards? For example,
She is coming toward you or towards you.
‘Toward’ or ‘towards’ (variant of ‘toward’) can only be a preposition or an adjective; it’s not a verb. In AmE, it’s mostly " She is coming toward you."
They're interchangeable, I agree, but could there have been at one time a difference between toward (a preposition) and towards (an adverb)? Check out the discussion here Tenser, said the Tensor: Toward and Towards (Take a look at the post by paul (gnfti) at Jul 29, 2004 12:48:44 AM).
The main difference between these two words is usage. "Toward" is used more in American English; "towards" is used in British English. Otherwise, they are interchangeable.
