Frost’s on radio, as he does with TV (6)
I believe the answer is:
rhymes
'he does with tv' is the definition.
The definition suggests a singular noun but the answer is a plural noun.
'frost's on radio as' is the wordplay.
'frost' becomes 'rime' (rime is frost by freezing water vapour).
'on radio' shows a homophone (sound like).
'as' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'rime' is a homophone of 'rhyme'.
'rhyme'+'s'='RHYMES'
Can you help me to learn more?
