Make point in case (6)
I believe the answer is:
'make' is the definition.
(I know that make can be written as create)
'point in case' is the wordplay.
'point' becomes 'e' (compass point).
'in' indicates putting letters inside.
'case' becomes 'crate' (crating is a kind of casing).
'e' put within 'crate' is 'CREATE'.
(Other definitions for create that I've seen before include "Bring into existence" , "Make, generate" , "Concoct" , "Make a fuss (colloq.)" , "coin" .)
