On the radio, channel ran well (4)
I believe the answer is:
flew
'ran well' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'on the radio channel' is the wordplay.
'on the radio' indicates a 'sounds like' (homophone) clue.
'channel' becomes 'flue' (flue is a kind of channel).
'flue' sounds like 'FLEW'.
Can you help me to learn more?
(Other definitions for flew that I've seen before include "Rushed (by air?)" , "lip" , "Travelled by air" , "Sped" , "Rushed < from local flat" .)
