Donkey concealed amongst llamas, surprisingly (3)
I believe the answer is:
ass
'donkey' is the definition.
(I've seen this before)
'concealed amongst llamas surprisingly' is the wordplay.
'concealed' says the answer is hidden in the clue.
'ASS' is hidden within 'amongst llamas surprisingly'.
(Other definitions for ass that I've seen before include "Hardy and sure-footed animal" , "oaf" , "Clot" , "Long-eared animal" , "Silly fool or beast of burden" .)
