Lived at Wembley Central, even (4)
I believe the answer is:
been
'lived' is the definition.
The answer and definition can be both to do with fundamental existence as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'at wembley central even' is the wordplay.
'at' says to put letters next to each other.
'central' indicates the central letters.
'even' becomes 'een' ('e'en' can be a synonym of 'even').
The centre of 'wembley' is 'b'.
'b'+'een' is 'BEEN'.
Can you help me to learn more?
(Other definitions for been that I've seen before include "(Have) gone in the past (to somewhere)" , "Past participle of be" .)
