First couple of letters on counter tucked away to send (5)
I believe the answer is:
elate
'send' is the definition.
(I've seen this in another clue)
'first couple of letters on counter tucked away' is the wordplay.
'first' is a charade indicator (letters next to each other).
'couple of letters on counter' becomes 'el' (I can't justify this - if you can you should give a lot more credence to this answer).
'tucked away' becomes 'ate' (I've seen this in another clue).
'el'+'ate' is 'ELATE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for elate that I've seen before include "Bring joy" , "Inspirit, make exultant" , "Make delighted or proud" , "transport?" , "Overjoy" .)
