Abandon one consumed by record hit (8)
I believe the answer is:
disclaim
'abandon' is the definition.
(both can mean to disown or reject)
'one consumed by record hit' is the wordplay.
'one' becomes 'I' (roman numeral).
'consumed by' indicates putting letters inside.
'record' becomes 'disc' (synonyms).
'hit' becomes 'lam' (to 'lam' means to hit hard).
'disc'+'lam'='disclam'
'i' put into 'disclam' is 'DISCLAIM'.
(Other definitions for disclaim that I've seen before include "Forswear" , "Renounce" , "Deny or relinquish" , "Disown or deny, maybe responsibility" , "Deny, refuse to acknowledge" .)
