Give medical attention again in an asylum, perhaps (7)

Ross

I believe the answer is:

retreat

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

'give' is the definition.
(thesaurus)

'medical attention again in an asylum perhaps' is the wordplay.
I cannot really see how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is found within the answer.
'an' could be 'a' and 'a' is located in the answer.
The remaining letters 'tret' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for retreat that I've seen before include "secluded place" , "It may be secluded" , "Tree rat (anag)" , "The Priory, say" , "place for meditation" .)
