Drinks left with a final note (4)
I believe the answer is:
laps
'drinks' is the definition.
(lapping is a kind of drinking)
'left with a final note' is the wordplay.
'left' becomes 'l' (common abbreviation).
'with' means one lot of letters go next to another.
'final note' becomes 'ps' (a PS or postscript in a letter. I am not sure about the 'final' bit.).
'l'+'a'+'ps'='LAPS'
Can you help me to learn more?
(Other definitions for laps that I've seen before include "Pals doing rounds of the track" , "Drinks; circuits" , "Circuits of track" , "Scoops up with the tongue" , "Circuits of a racetrack" .)
