Libyans primarily seen in visit over here! (7)
I believe the answer is:
tripoli
'here' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'libyans primarily seen in visit over' is the wordplay.
'primarily' indicates taking the first letters.
'seen in' indicates putting letters inside.
'visit' becomes 'trip' (trip can mean a visit or holiday somewhere).
'over' becomes 'oi' (I can't explain this - if you can you should believe this answer much more).
The first letter of 'libyans' is 'l'.
'trip'+'oi'='tripoi'
'l' put inside 'tripoi' is 'TRIPOLI'.
Can you help me to learn more?
(Other definitions for tripoli that I've seen before include "Libyan capital" , "North African capital" , "city on the Mediterranean" , "where there's been regime change" , "Capital of Libya" .)
