Take as a loan (6)
I believe the answer is:
borrow
'take as a loan' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for borrow that I've seen before include "Receive as a loan" , "Beg, ...... or steal - get at all costs" , "Take with the intention of returning" , "Take with (or without!) permission" , "Accept a loan" .)
