Give a star, maybe (4)
I believe the answer is:
rate
'give a star maybe' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rate that I've seen before include "Adjudge" , "The percentage of a loan charged as interest" , "quality" , "Be worthy of; speed" , "Measure of frequency; merit" .)
