Cover point, he catches Cook (7)
I believe the answer is:
sheathe
'cover' is the definition.
(sheathing is a kind of covering)
'point he catches cook' is the wordplay.
'point' becomes 's' (S is an example).
'catches' indicates putting letters inside.
'cook' becomes 'heat' (I've seen this before).
's'+'he'='she'
'she' going around 'heat' is 'SHEATHE'.
(Other definitions for sheathe that I've seen before include "Put (a sword) into its holder" , "Put (a sword) into case" , "Put (a sword) it its cover" , "Protective cover, for sword say" , "Encase in protection" .)
