Tiny look over northern city of old (7)
I believe the answer is:
babylon
'city of old' is the definition.
(ancient city)
'tiny look over northern' is the wordplay.
'tiny' becomes 'baby' (I can't explain this - if you can you should believe this answer much more).
'look' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'over' means one lot of letters go next to another.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'baby'+'lo'+'n'='BABYLON'
Can you help me to learn more?
(Other definitions for babylon that I've seen before include "Sin City of the Bible" , "Bony lab found in the ancient city" , "Bony lab in the old city of Mesopotamia" , "Chief city of ancient Mesopotamia" , "Wicked city of the Bible, on Euphrates river in central Iraq" .)
