Tribal struggles in Gabon are reduced in disputed territory (9)
I believe the answer is:
gibraltar
'disputed territory' is the definition.
(I've seen this before)
'tribal struggles in gabon are reduced' is the wordplay.
'struggles' indicates an anagram.
'in' indicates putting letters inside.
'gabon' becomes 'g' (this could be a standard abbreviation of which I'm unaware).
'reduced' means to remove the last letter.
'tribal' anagrammed gives 'ibralt'.
'are' with its last letter taken off is 'ar'.
'g'+'ar'='gar'
'ibralt' going within 'gar' is 'GIBRALTAR'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for gibraltar that I've seen before include "Great rock at south of Spain" , "British dependency" , "British overseas territory" , "disputed territory" , "Mediterranean port" .)
