Delicate proposal (6)
I believe the answer is:
tender
This clue is a double definition.
'delicate' is the first definition.
(similar in meaning)
'proposal' is the second definition.
(I've seen this before)
(Other definitions for tender that I've seen before include "Easy to cut or chew" , "Loving, not tough" , "Legal ..., official money" , "A gentle kind of bid" , "sensitive > carer > money" .)
