Intend to get work in writing (7)
I believe the answer is:
Here is my best explanation:
'intend' is the definition.
(proposing is a kind of intending)
'work in writing' is the subsidiary indication.
'work' becomes 'op' (common abbreviation for 'opus').
'in' is an insertion indicator.
'writing' becomes 'prose' (I've seen this in other clues**).
'op' put into 'prose' is 'propose'.
'to get' is the link.
(Other definitions for propose that I've seen before include "Put forward a plan", "Intend", "Put forward for consideration", "advance", "Tender", "Present for consideration", "Suggest - make an offer", "Put forward (an idea)", "Request" and "table".)
