Groom feathers (5)
I believe the answer is:
preen
'groom feathers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for preen that I've seen before include "setdown straight?" , "Tidy/clean (feathers)" , "Dress or smooth, feathers say" , "Congratulate (oneself); attend to dress" , "Groom with elaborate care" .)
