Pay silent attention (6)

Ross

I believe the answer is:

listen

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

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

'silent attention' is the wordplay.
'silent' can be anagrammed to 'LISTEN'.
However, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for listen that I've seen before include "Hark!" , "Attend (to a sound)" , "Take heed -- 13 (anag)" , "16 (anag.)" , "Respond to a request" .)
