Cringe — grovel (5)
I believe the answer is:
crawl
This clue is a double definition.
'cringe' is the first definition.
(I know that cringe can be written as crawl)
'grovel' is the second definition.
(I know that grovel can be written as crawl)
(Other definitions for crawl that I've seen before include "Move as snakes do, or on hands and knees" , "Make no haste" , "Move slowly (as a baby does?)" , "Slow advance" , "Baby-like advance" .)
