In Paris, one never winds alarm (7)
I believe the answer is:
unnerve
'alarm' is the definition.
(thesaurus)
'in paris one never winds' is the wordplay.
I cannot really understand how this works, but
'one' could be 'un' (northern English dialect form of 'one') and 'un' is located in the answer.
an anagram of 'never' is 'nerve' which is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for unnerve that I've seen before include "Dishearten - discourage" , "worry" , "Faze" , "To startle" , "Psych out" .)
