Animal deliberately enclosed (5)
I believe the answer is:
ratel
'animal' is the definition.
(I've seen this before)
'deliberately enclosed' is the wordplay.
'enclosed' indicates the answer is hidden within the clue (the answer is enclosed within the clue).
'RATEL' can be found hidden inside 'deliberately'.
(Other definitions for ratel that I've seen before include "wild animal" , "Badger-like animal" , "Honey-badger" , "creature with sweet tooth" , "Badger-like creature" .)
