Bond, that fellow in a dress abandoning ship (6)
I believe the answer is:
adhere
'bond' is the definition.
(synonyms)
'fellow in a dress abandoning ship' is the wordplay.
'fellow' becomes 'he' ('he' refers to a man).
'in' indicates putting letters inside.
'abandoning' is a deletion indicator.
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'dress' with 'ss' taken away is 'dre'.
'a'+'dre'='adre'
'he' going inside 'adre' is 'ADHERE'.
'that' acts as a link.
(Other definitions for adhere that I've seen before include "'Stick to, a play say (6)'" , "Cling, attach" , "Stick fast (to something)" , "paste" , "Stick to, cling" .)
