Old restaurant keeping cold fish out (7)
I believe the answer is:
extract
'fish out' is the definition.
Both the definition and answer are verbs in their base form.
Maybe they are linked in a way I don't understand?
'old restaurant keeping cold' is the wordplay.
'old' becomes 'ex'.
'restaurant' becomes 'trat' (I've seen this in other clues).
'keeping' indicates putting letters inside.
'cold' becomes 'c' (eg on taps).
'trat' enclosing 'c' is 'tract'.
'ex'+'tract'='EXTRACT'
Can you help me to learn more?
(Other definitions for extract that I've seen before include "concentrate" , "Clipping" , "Pull or take out - maybe a tooth" , "Cutting" , "selection" .)
