Tenor leaving to peer (4)
I believe the answer is:
toff
'peer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'tenor leaving' is the wordplay.
'tenor' becomes 't'.
'leaving' becomes 'off' ('I'm off' means 'I'm leaving').
't'+'off'='TOFF'
'to' is the link.
Can you help me to learn more?
(Other definitions for toff that I've seen before include "Person of the upper classes" , "Dandy" , "Aristo" , "Rich person (colloq.)" , "Posh type" .)
