Get paid for learning to go without fish (4)

I believe the answer is:

earn

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

'get paid' is the definition.
(I've seen this before)

'learning to go without fish' is the wordplay.
'EARN' is hidden in amongst the letters.
But, I'm not sure how the hidden word is indicated.

'for' is the link.

Can you help me to learn more?

(Other definitions for earn that I've seen before include "Merit (a reward)" , "Pull in" , "Twist out of shape" , "There's merit" , "Take in bread" .)

I've seen this clue in the Evening Standard.
