Gradually decreases (5)

Ross

I believe the answer is:

wanes

(Other definitions for wanes that I've seen before include "Decreases in vigour or strength like the moon" , "Grows smaller like the moon" , "Gradually declines" , "Of the moon, gradually decreases" .)

I've seen this clue in the USA Today and The Irish Times.
