Part of Shakespearean range (4)
I believe the answer is:
area
'range' is the definition.
(thesaurus)
'part of shakespearean' is the wordplay.
'part of' says the answer is hidden in the clue.
'AREA' is hidden in the letters of 'shakespearean'.
(Other definitions for area that I've seen before include "Geographical region" , "Space for a specific purpose, say picnic" , "Locality" , "The measure of a surface" , "Extent of a two-dimensional surface" .)
