Look fixedly (5)
I believe the answer is:
stare
'look fixedly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stare that I've seen before include "'Look fixedly, without blinking (5)'" , "Rates (anag.)" , "Long fixed look" , "Gaze fixedly" , "Look with fixed gaze" .)
