Hide from view regularly car seat's splits (7)
I believe the answer is:
secrete
'hide' is the definition.
(I've seen this in another clue)
'view regularly car seat's splits' is the wordplay.
'view' becomes 'see' (synonyms).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'splits' means one lot of letters goes inside another (inserted letters split open the word).
'car'+'seat'='carseat'
The alternate letters of 'carseat' are 'cret'.
'see' going around 'cret' is 'SECRETE'.
'from' is the link.
(Other definitions for secrete that I've seen before include "Hide away" , "squirrel" , "harbour" , "Hide - discharge" , "Place out of sight, hide" .)
