What's commercial TV read out? (6)
I believe the answer is:
advert
'what's commercial' is the definition.
(I've seen this before)
'tv read out?' is the wordplay.
'out?' indicates an anagram (out can mean wrong or inaccurate).
'tv'+'read'='tvread'
'tvread' with letters rearranged gives 'ADVERT'.
(Other definitions for advert that I've seen before include "Bill" , "Commercial notice" , "Refer; commercial" , "Draw attention to" , "Plug (abbr)" .)
