Resident sharing a room with some citizens (7)
I believe the answer is:
denizen
'resident' is the definition.
(I've seen this before)
'sharing a room with some citizens' is the wordplay.
I cannot really understand how this works, but
'room' could be 'den' (den is a kind of room) and 'den' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for denizen that I've seen before include "Enid Zen (anag) - inhabitant of a particular place" , "Resident" , "Person in foreign country enjoying rights of natives" , "Dweller" , "Inhabitant (of the deep?)" .)
