Where those who board get off? (4)
I believe the answer is:
dorm
'where those who board get off?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for dorm that I've seen before include "Boarding school bedroom (abbr)" , "Rest area" , "place to sleep" , "where many crash" , "Sleeping quarters (abbr)" .)
