Mendicant monk (5)
I believe the answer is:
friar
'mendicant monk' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for friar that I've seen before include "Mendicant monk" , "Eg, a Dominican" , "he offers religious teaching?" , "Eg, a Franciscan" , "Mendicant preacher" .)
