Have a look around the South as well (4)
I believe the answer is:
also
'as well' is the definition.
(synonyms)
'have a look around the south' is the wordplay.
'have a look' becomes 'alo' (I am not sure about this - if you are sure you should believe this answer much more).
'around' indicates putting letters inside.
'the south' becomes 's' (abbreviation).
'alo' enclosing 's' is 'ALSO'.
Can you help me to learn more?
