I believe the answer is:

earn

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

This could be a double definition.

'acquire' is the first definition.
(earning is a kind of acquiring)

'said crock?' is the second definition.
Although both the answer and definition are verbs in their base form, I don't understand how one could define the other.

Can you help me to learn more?

(Other definitions for earn that I've seen before include "Acquire by one's efforts" , "Be paid for work" , "Secure" , "Deserve; get paid" , "and 3: Work for bed and board" .)
