I believe the answer is:

tolled

I'm a little stuck... Click here to teach me more about this clue!

'charged' is the definition.
Although both the answer and definition are past participle verbs, I can't understand how one could define the other.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for tolled that I've seen before include "Rang, or charged for using" , "Of bell, rang sonorously" , "Made slow sounds" , "Sounded the bell" , "Of bell, rang solemnly" .)
