Lent may be brought forward (8)
I believe the answer is:
advanced
This clue is a double definition.
'lent' is the first definition.
(advancing is a kind of lending)
'brought forward' is the second definition.
('advance' can be a synonym of 'bring forward')
'may be' is the link.
(Other definitions for advanced that I've seen before include "not for a beginner" , "Sophisticated" , "Moved forward" , "Hi-tec truck" , "subbed" .)
