Propose movement forward (7)
I believe the answer is:
advance
This clue is a double definition.
'propose' is the first definition.
(advancing is a kind of proposing)
'movement forward' is the second definition.
(I've seen this before)
(Other definitions for advance that I've seen before include "Forward movement, a change for the better" , "Payment ahead of due date (1'7)" , "Move forward to get loan?" , "Lend money on security" , "Go forwards" .)
