Did he rest on the bed after tea? (7)
I believe the answer is:
charlie
'did he rest on' is the definition.
The definition suggests a singular noun which matches the answer.
'bed after tea?' is the wordplay.
'bed' becomes 'lie' (I can't justify this - if you can you should believe this answer much more).
'after' is a charade indicator (letters next to each other).
'tea?' becomes 'char' (I've seen this before).
'lie' after 'char' is 'CHARLIE'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for charlie that I've seen before include "Cocaine (colloq.), fool (colloq.)" , "-- Chaplin" , "succeeds. Bravo!" , "Fool - drug (slang)" , "Code word for letter C" .)
