Sensitive editor made an offer (8)
I believe the answer is:
tendered
'made an offer' is the definition.
(I've seen this in another clue)
'sensitive editor' is the wordplay.
'sensitive' becomes 'tender' (synonyms).
'editor' becomes 'ed' (abbreviation).
'tender'+'ed'='TENDERED'
(Other definitions for tendered that I've seen before include "Offered as at auction" , "Offered a bid for a contract" , "submitted" , "Proffered" , "Put in a bid for a contract" .)
