Raised collection when in distress (5)
I believe the answer is:
upset
'in distress' is the definition.
'upset' can be an answer for 'distress' (I've seen this before). I am not certain of the 'in' bit.
'raised collection' is the wordplay.
'raised' becomes 'up' (similar in meaning).
'collection' becomes 'set' (set is a kind of collection).
'up'+'set'='UPSET'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for upset that I've seen before include "Disturb(ance)" , "Disturbed or capsized" , "Disturbed or knocked out of place" , "Knock over; worried" , "Indisposition" .)
