Was affected by low temperature and became statuesque (5)
I believe the answer is:
froze
'statuesque' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for froze that I've seen before include "E.g. turned to ice" , "Suddenly stood motionless" , "Stopped dead" , "suddenly stopped" , "Became immobilised" .)
