Taped broadcast, including name for purist (6)
I believe the answer is:
pedant
'purist' is the definition.
(I've seen this before)
'taped broadcast including name' is the wordplay.
'broadcast' indicates an anagram (letters scattered or cast around).
'including' indicates putting letters inside.
'name' becomes 'n' (common abbreviation e.g. on forms).
'taped' anagrammed gives 'pedat'.
'pedat' going around 'n' is 'PEDANT'.
'for' is the link.
(Other definitions for pedant that I've seen before include "Purist" , "Panted like stickler for accuracy" , "formalist" , "Person who pays too much attention to formal rules" , "Stickler for the rules" .)
