Country girl on booze university … (8)
I believe the answer is:
portugal
'country' is the definition.
(Portugal is an example)
'girl on booze university' is the wordplay.
'girl' becomes 'gal' (synonyms).
'on' means one lot of letters go next to another.
'booze' becomes 'port'.
'university' becomes 'u'.
'port'+'u'='portu'
'gal' after 'portu' is 'PORTUGAL'.
(Other definitions for portugal that I've seen before include "in E" , "EU member state" , "Country formerly ruled by Antonio de Oliveira Salazar" , "Its capital is Lisbon" , "Southwest European country" .)
