Tell it differently, just a bit (6)
I believe the answer is:
little
'just a bit' is the definition.
(thesaurus)
'tell it differently' is the wordplay.
'differently' indicates anagramming the letters.
'tell'+'it'='tellit'
'tellit' is an anagram of 'LITTLE'.
(Other definitions for little that I've seen before include "Jobsworth?" , "Teensy-weensy" , "Tiny" , "Not big, much or important" , "(Heroine of) Dickens novel" .)
