Closer? Loves to be held by doctor (4)
I believe the answer is:
door
'closer? loves to be held by doctor' is the definition.
I can't tell whether this defines the answer.
'loves to be held by doctor' is the wordplay.
'loves' becomes 'oo' (love means 0 in tennis).
'to be held by' means one lot of letters goes inside another.
'doctor' becomes 'dr' (abbreviation).
'oo' inserted inside 'dr' is 'DOOR'.
Can you help me to learn more?
(Other definitions for door that I've seen before include "place of entry" , "Entry point" , "Barrier to open and close" , "Means of exit and entrance" , "Jim Morrison?" .)
