Ends giving clues (4)
I believe the answer is:
tips
This clue is a double definition.
'ends' is the first definition.
(the tips of something are its ends)
'clues' is the second definition.
(a tip is a hint or clue)
'giving' acts as a link.
(Other definitions for tips that I've seen before include "Useful hints" , "Ends" , "extra payments" , "Gratuties" , "Turns over" .)
