Semi-humans interrupted at home (9)
I believe the answer is:
apartment
'home' is the definition.
(I know that apartment is a type of home)
'semi-humans interrupted' is the wordplay.
I cannot really understand how this works, but
'humans' could be 'tmen' (T-man is an example) and 'tmen' is located in the answer.
The remaining letters 'apart' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'at' acts as a link.
Can you help me to learn more?
(Other definitions for apartment that I've seen before include "Penthouse" , "Accommodation" , "Suite of rooms to live in" , "place to live" , "quarters" .)
