Snuggle (in) (6)
I believe the answer is:
nestle
'snuggle in' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nestle that I've seen before include "They make 6 [SNACK BARS]" , "Cuddle, curl up" , "Snuggle into, say, embrace" , "Lie safely" , "Be snug as a baby bird" .)
