'odd' is the definition.
(both can mean unusual)

'city money leading to wealth not half?' is the wordplay.
'city' becomes 'EC' (the City of London postcode).
'money leading' becomes 'cent' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to wealth' becomes 'riches' (synonyms).
'not half?' suggests halving the letters.
'riches' with half the letters taken is 'ric'.
'ec'+'cent'+'ric'='ECCENTRIC'

Can you help me to learn more?
