Fancy android eating sandwiches! (4)
I believe the answer is:
idea
'fancy' is the definition.
(I've seen this in another clue)
'android eating sandwiches' is the wordplay.
'sandwiches' indicates a hidden word (the answer is sandwiched in by the clue).
'IDEA' is hidden within 'android eating'.
(Other definitions for idea that I've seen before include "Intention" , "Light bulb above head" , "Plan" , "Sudden inspiration?" , "Brainwave" .)
