Destabilise Lagos: no second aim (4)
I believe the answer is:
goal
'aim' is the definition.
(I've seen this before)
'destabilise lagos no second' is the wordplay.
I cannot quite understand how this works, but
'no' could be 'o' (O resembles 0) and 'o' is located in the answer.
The remaining letters 'gal' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for goal that I've seen before include "Soccer achievement" , "Target, objective" , "Football score" , "Objective or score" , "Object, aim" .)
