Tuck, perhaps (5)
I believe the answer is:
friar
'tuck' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for friar that I've seen before include "Member of one of the four mendicant orders" , "Religious brother" , "Religious man" , "Mendicant priest" , "he offers religious teaching?" .)
