Move end of project to get financial allowance (6)
I believe the answer is:
budget
'financial allowance' is the definition.
(a budget is an allowance of money)
'move end of project' is the wordplay.
'move' becomes 'budge' (to budge is to move slightly).
'end of' suggests the final letters.
The last letter of 'project' is 't'.
'budge'+'t'='BUDGET'
'to get' acts as a link.
(Other definitions for budget that I've seen before include "Plan of income and expenditure" , "Money allocated for a purpose" , "Plan of spending" , "Plan financially" , "Limit of funds" .)
