Admitted by Italian monk, look at plants (5)
I believe the answer is:
flora
'plants' is the definition.
(I've seen this before)
'admitted by italian monk look' is the wordplay.
'admitted by' indicates putting letters inside.
'italian monk' becomes 'fra' (I've seen this before).
'look' becomes 'lo'.
'fra' going around 'lo' is 'FLORA'.
'at' is the link.
(Other definitions for flora that I've seen before include "For example, Miss Macdonald" , "growing things" , "Plants collectively" , "collection of plants" , "Plant life (to go with fauna)" .)
