Is Head of Eton stopping lesson being broadcast still? (9)
I believe the answer is:
noiseless
'still?' is the definition.
(thesaurus)
'is head of eton stopping lesson being broadcast' is the wordplay.
'head of' says to take the initial letters.
'stopping' is an insertion indicator (stopping can mean blocking a gap).
'being broadcast' indicates an anagram.
The initial letter of 'eton' is 'e'.
'is'+'e'='ise'
'lesson' with letters rearranged gives 'noless'.
'ise' inserted within 'noless' is 'NOISELESS'.
(Other definitions for noiseless that I've seen before include "Silent, quiet" , "Lionesses (anag) - making no sound" , "unsound?" , "with a silencer?" , "Mum" .)
