Was Jim Morrison one getting closer? (4)
I believe the answer is:
door
'one getting closer?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for door that I've seen before include "Jim Morrison?" , "Threshold" , "Alternative to knocker" , "Barrier to open and close" , "Entrance to room, house etc" .)
