Sailor accustomed to being reviled (6)
I believe the answer is:
abused
'being reviled' is the definition.
('abused' can be similar in meaning to 'reviled')
'sailor accustomed' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'accustomed' becomes 'used' (I've seen this in other clues).
'ab'+'used'='ABUSED'
'to' acts as a link.
(Other definitions for abused that I've seen before include "Swore at" , "Reviled, called nasty names" , "vilified" , "Wrongfully treated" , "were cruel to partners!" .)
