Uncovered name of television pioneer, we hear (5)
I believe the answer is:
bared
'uncovered' is the definition.
(baring is a kind of uncovering)
'name of television pioneer we hear' is the wordplay.
'name of television pioneer' becomes 'baird' (John Logie Baird).
'we hear' shows a homophone (sound like).
'baird' sounds like 'BARED'.
(Other definitions for bared that I've seen before include "Uncovered" , "Stripped" .)
