Be a predictor of good area for wine shop (6)
I believe the answer is:
bodega
'for wine shop' is the definition.
(I've seen this before)
'be a predictor of good area' is the wordplay.
'be a predictor of' becomes 'bode' (I can't justify this - if you can you should give a lot more credence to this answer).
'good' becomes 'g' (abbreviation).
'area' becomes 'a' (maths abbreviation).
'bode'+'g'+'a'='BODEGA'
Can you help me to learn more?
(Other definitions for bodega that I've seen before include "warehouse for wine" , "Small Spanish grocery and wine store" , "Spanish grocery and wine shop" , "concern for alcohol" , "booze shop" .)
