Kind offer (6)
I believe the answer is:
This clue is a double definition.
'kind' is the first definition.
(tender can mean kind or thoughtful)
'offer' is the second definition.
(tender can mean to offer something)
(Other definitions for tender that I've seen before include "Offer; delicate" , "Offer, gentle, boat" , "Delicate sort of bid" , "easily damaged" , "Put in a bid" .)
