In rage, give out pain (8)

Ross

I believe the answer is:

aggrieve

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

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

'in rage give' is the wordplay.
'rage give' anagrams to 'AGGRIEVE'.
However, I am unsure how this is indicated.

'out' acts as a link.

Can you help me to learn more?

(Other definitions for aggrieve that I've seen before include "Break the heart" , "Distress (someone)" , "Hurt" , "Cause to feel sorrow" , "Trouble" .)
