Grand soda hunt abandoned (8)
I believe the answer is:
thousand
'grand' is the definition.
(synonyms)
'soda hunt abandoned' is the wordplay.
'abandoned' indicates anagramming the letters (the original order is abandoned).
'soda'+'hunt'='sodahunt'
'sodahunt' anagrammed gives 'THOUSAND'.
(Other definitions for thousand that I've seen before include "Large number" , "in MCC, but missing double century" , "Ten hundred" , "Ten hundreds" , "Figure" .)
