Regularly narrates tricks (4)
I believe the answer is:
arts
'tricks' is the definition.
(I've seen this before)
'regularly narrates' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternate letters of 'narrates' are 'ARTS'.
(Other definitions for arts that I've seen before include "Humanities" , "Star over aesthetic endeavours" , "Literature, music etc." , "Non-science subjects" , "Drawing, painting, etc" .)
