Curious disposition around City is on the level? (9)
I believe the answer is:
recumbent
'on the level?' is the definition.
I can't judge whether this defines the answer.
'curious disposition around city' is the wordplay.
'curious' becomes 'rum' (synonyms).
'disposition' becomes 'bent' (bent is a kind of disposition).
'around' means one lot of letters goes inside another.
'city' becomes 'EC' (the City of London postcode).
'rum'+'bent'='rumbent'
'rumbent' enclosing 'ec' is 'RECUMBENT'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for recumbent that I've seen before include "flat?" , "Lying down comfortably" .)
