Tearier drunk in African country (7)
I believe the answer is:
eritrea
'african country' is the definition.
(country in Africa)
'tearier drunk' is the wordplay.
'drunk' is an anagram indicator.
'tearier' with letters rearranged gives 'ERITREA'.
'in' acts as a link.
(Other definitions for eritrea that I've seen before include "NE African country" , "River forming part of German-Polish border" , "North-east African state" , "It became independent of Ethiopia in 1993" , "Eire art (anag)" .)
