Vigor (sic) in volume in vogue upset (7)
I believe the answer is:
vinegar
'vigor sic' is the definition.
I can't tell whether this defines the answer.
'volume in vogue upset' is the wordplay.
'volume' becomes 'v'.
'vogue' becomes 'rage' (rage is a kind of vogue).
'upset' says the letters should be written in reverse.
'rage' reversed gives 'egar'.
'v'+'in'+'egar'='VINEGAR'
'in' is the link.
Can you help me to learn more?
(Other definitions for vinegar that I've seen before include "Soured wine, cider etc." , "Sour-tasting liquid as condiment" , "Acetic acid" , "Condiment - bad temper" , "Ill-temper" .)
