Lent is brought forward (8)
I believe the answer is:
advanced
I believe 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')
'is' acts as a link.
(Other definitions for advanced that I've seen before include "Hi-tec truck" , "Far ahead in development or progress" , "At a higher level" , "Lent - ahead in development" , "Far on; complex" .)
