Differing form of a diver (6)
I believe the answer is:
varied
'differing' is the definition.
(I've seen this before)
'form of a diver' is the wordplay.
'form of' is an anagram indicator (the letters need to be in another 'form').
'a'+'diver'='adiver'
'adiver' anagrammed gives 'VARIED'.
(Other definitions for varied that I've seen before include "Differing" , "Of different sorts, diverse" , "(Of selection) showing a number of types" , "Of different kinds" , "Mixed" .)
