Tune left for John Lennon, for example (7)
I believe the answer is:
airport
'john lennon for example' is the definition.
I can't tell whether this definition defines the answer.
'tune left' is the wordplay.
'tune' becomes 'air' (air can mean a piece of music).
'left' becomes 'port' (left side of a ship - opposite of starboard).
'air'+'port'='AIRPORT'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for airport that I've seen before include "Place of takeoffs and landings" , "passenger terminal" , "Transport hub" , "See 18" , "where flight begins or ends" .)
