We are not in hot water finding the frog there (6)
I believe the answer is:
throat
'water finding the frog there' is the definition.
I can't judge whether this defines the answer.
'we are not in hot' is the wordplay.
I cannot really see how this works, but
'are' could be 'a' (the 'are' is a metric unit of area) and 'a' is found in the answer.
'hot' could be 'h' and 'h' is found in the answer.
The remaining letters 'trot' is a valid word 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 throat that I've seen before include "The pharynx" , "Passage from the back of the mouth" , "Gorge - frog's location?" , "A frog is a problem in this" , "Forepart of the neck" .)
