Some like sandwiches (honey?) (3)
I believe the answer is:
'honey?' is the definition.
(Latin name for honey)
'some like sandwiches' is the wordplay.
'sandwiches' indicates the answer is hidden within the clue (the answer is sandwiched in by the clue).
'MEL' is hidden within 'some like'.
(Other definitions for mel that I've seen before include "-- Brooks, film director" , "Honey" , "- - Gibson (actor)" .)
