Sense to ask for a loan (5)
I believe the answer is:
touch
I believe this clue is a double definition.
'sense' is the first definition.
(I know that touch is a sense)
'ask for a loan' is the second definition.
(I've seen this in another clue)
'to' is the link.
(Other definitions for touch that I've seen before include "Make physical contact" , "kiss" , "spot" , "Handle; feel" , "Deftness" .)
