Cashew or almond (3)
I believe the answer is:
nut
I believe this clue is a double definition.
'cashew' is the first definition.
(I've seen this in another clue)
'almond' is the second definition.
(thesaurus)
(Other definitions for nut that I've seen before include "Vegetarian food" , "Screwball" , "Fruit with hard shell" , "Fruitcake" , "Large, hard-shelled seed" .)
