Republic in the middle of Brazil shot bear one month (10)
I believe the answer is:
azerbaijan
'republic' is the definition.
(I've seen this before)
'middle of brazil shot bear one month' is the wordplay.
'middle of' indicates the central letters.
'shot' indicates anagramming the letters.
'one' becomes 'i' (Roman numeral).
'month' becomes 'jan' (Jan is short for January).
The centre of 'brazil' is 'az'.
'bear' is an anagram of 'erba'.
'az'+'erba'+'i'+'jan'='AZERBAIJAN'
'in the' acts as a link.
(Other definitions for azerbaijan that I've seen before include "in Asia" , "Baku's country" , "Country in the South Caucasus" , "republic" .)
