Strict with new pointer (6)
I believe the answer is:
narrow
'strict' is the definition.
(narrow can mean strict or precise)
'with new pointer' is the wordplay.
'with' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'pointer' becomes 'arrow' (synonyms).
'n' next to 'arrow' is 'NARROW'.
(Other definitions for narrow that I've seen before include "Constricted in width" , "With sides close together" , "Closely confining" , "Meagre, confined" , "Restrict" .)
