East side of city on Dee, Aberdeen’s over there (4)

'over there' is the definition.
(I've seen this in another clue)

'east side of city on dee' is the wordplay.
'east side of' suggests halving the letters (the right or 'east' half of the word).
'city' becomes 'NY' (short for New York).
'dee' becomes 'd'.
'ny' halved is 'y'.
'y'+'on'+'d'='YOND'

'aberdeen's' acts as a link.
This may not be right. It may be part of another bit of the clue.

Can you help me to learn more?
