Literary group becomes ragged on the radio? (6)
I believe the answer is:
phrase
'literary group' is the definition.
(group of words)
'becomes ragged on the radio?' is the wordplay.
'becomes ragged' becomes 'frays' (I've seen this in another clue).
'on the radio?' shows a homophone (sound like) (I've seen 'on the radio' mean this).
'frays' is a homophone of 'PHRASE'.
(Other definitions for phrase that I've seen before include "Group of words/notes" , "few words from a tourist guide?" , "Word (in a particular way)" , "Group of words forming part of a sentence" , "Mode of expression" .)
