Noble, like the News at Ten broadcast? (8)
I believe the answer is:
knightly
'noble' is the definition.
(thesaurus)
'like the news at ten broadcast?' is the wordplay.
'like the news at ten' becomes 'nightly'.
'broadcast?' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'nightly' sounds like 'KNIGHTLY'.
(Other definitions for knightly that I've seen before include "Valiant and chivalrous" , "Noble" .)
