Bewildered when temperature rises in a constituency (2,3)
I believe the answer is:
at sea
'bewildered' is the definition.
(synonyms)
'when temperature rises in a constituency' is the wordplay.
I cannot really understand how this works, but
'temperature' could be 't' (abbreviation) and 't' is located in the answer.
'when' could be 'as' (eg 'when I walked' means 'as I walked') and 'as' is found within the leftover letters.
'a' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for at sea that I've seen before include "pirate's probable position?" , "Sailing off shore" , "Sailing - confused" , "cruising?" , "Perplexed" .)
