Cuddle intense talker regularly (6)
I believe the answer is:
nestle
'cuddle' is the definition.
(I know that cuddle can be written as nestle)
'intense talker regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'intense'+'talker'='intensetalker'
The alternating letters of 'intensetalker' are 'NESTLE'.
(Other definitions for nestle that I've seen before include "Lie snugly (in a place)" , "Lie (in sheltered place)" , "Lie safely" , "Be snug as a baby bird" , "Settle comfortably (against something)" .)
