Maybe Yoko and John's last English broadcast without anyone else (2,4,3)
I believe the answer is:
on ones own
'maybe' is the definition.
Both the definition and answer are adverbs. Perhaps they are linked in a way I don't understand?
'yoko and john's last english broadcast without anyone else' is the wordplay.
I cannot really see how this works, but
'yoko' could be 'ono' (musician Yoko Ono) and 'ono' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'broadcast' could be 'sown' (I've seen this before) and 'sown' is found within the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for on ones own that I've seen before include "Alone" , "Independently" , "Helpless" .)
