Right name for bad visibility or a cold wind (7)
I believe the answer is:
mistral
'wind' is the definition.
(mistral is a kind of wind)
'right name for bad visibility or a cold' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
'name' could be 'al' and 'al' is located in the answer.
The remaining letters 'mist' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for mistral that I've seen before include "That's a blow" , "Cold dry wind in southern France" , "Strong cold dry wind" , "Violent northeast wind of southern France" , "A harsh blow" .)
