Look for new rates (5)
I believe the answer is:
stare
'look' is the definition.
(I know that look is a is a more specific form of the action of stare)
'new rates' is the wordplay.
'new' indicates an anagram.
'rates' with letters rearranged gives 'STARE'.
'for' acts as a link.
(Other definitions for stare that I've seen before include "Gaze fixedly" , "Rates (anag.)" , "Long fixed look" , "Gawp" , "bird" .)
