Which word in the following sentence is modified by an adverb?

The soccer player forcefully kicked the ball.

A. Soccer

B. Player

C. Kicked

D. Ball

Adverbs typically answer questions like "how" and most commonly end in - ly (but don't be fooled, there's many, many more.)

In this sentence, "forcefully" is telling you HOW the soccer player kicked the ball. A is an adjective, B is a noun, C is a verb, and D is also a noun. Adverbs modify verbs, and since "forcefully" modifies "kicked," the answer is C.

I would say Kick. How did the player kick the ball. He kicked the ball forcefully
