City outing a little too lively (7)
I believe the answer is:
tripoli
'city' is the definition.
(Tripoli is an example)
'outing a little too lively' is the wordplay.
I cannot really understand how this works, but
'outing' could be 'trip' (I've seen this before) and 'trip' is found in the answer.
'little' could be 'l' (abbreviation for little) and 'l' is found in the answer.
The remaining letters 'oi' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tripoli that I've seen before include "Middle East port" , "Libyan port" , "North African city" , "Lebanese port" , "powdery deposit" .)
