About to have a short sleep before starting to eat a tasty tidbit (6)
I believe the answer is:
canape
'a tasty tidbit' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'about to have a short sleep before starting to eat' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa').
'to have' means one lot of letters go next to another.
'a short sleep' becomes 'nap' (a nap is a short sleep; 'short' indicates a short form).
'before' says to put letters next to each other.
'starting to' says to take the initial letters.
The initial letter of 'eat' is 'e'.
'ca'+'nap'+'e'='CANAPE'
Can you help me to learn more?
(Other definitions for canape that I've seen before include "Savoury titbit" , "Small item of food served with drinks" , "Piece of finger-food" , "Small thing to eat with a drink" , "Finger food for parties" .)
