French wine producer recruiting nurses (3)
I believe the answer is:
cru
'french wine' is the definition.
The definition suggests a singular noun which matches the answer.
'producer recruiting nurses' is the wordplay.
'nurses' indicates a hidden word (nurse can mean holding closely).
'CRU' is hidden within 'producer recruiting'.
Can you help me to learn more?
(Other definitions for cru that I've seen before include "Grounds for eg red" , "Vineyard or group of them in France" , "Group of vineyards" , "Source of wine" , "Source of alcohol" .)
