Is able to take off a cocktail savoury
I believe the answer is:
canape
'a cocktail savoury' is the definition.
'canape' can be an answer for 'savoury' (I've seen this before). I am unsure of the 'a cocktail' bit.
'is able to take off' is the wordplay.
'is able to' becomes 'can' (if you can do something you are able to do it).
'take off' becomes 'ape' (I've seen this in other clues).
'can'+'ape'='CANAPE'
Can you help me to learn more?
(Other definitions for canape that I've seen before include "Tasty morsel, with drinks perhaps" , "Small piece of bread or pastry spread with savoury" , "cocktail treat" , "Light refreshment" , "Savoury nibble offered at posh parties" .)
