Happen to be relegated (6)
I believe the answer is:
godown
'happen to be relegated' is the definition.
I can't tell whether this defines the answer.
'be relegated' is the wordplay.
'be' becomes 'go' (going is a kind of being).
'relegated' becomes 'down' (as in going down a league in football).
'go'+'down'='GODOWN'
Can you help me to learn more?
(Other definitions for godown that I've seen before include "storage facility in India" , "Leave university" , "eastern warehouse" .)
