Language evident in Sahara bickering (6)
I believe the answer is:
arabic
'language' is the definition.
(Arabic is a language)
'in sahara bickering' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ARABIC' is hidden in the letters of 'sahara bickering'.
'evident' acts as a link.
(Other definitions for arabic that I've seen before include "Major language of Middle East" , "Language of the Koran" , "1 [GCSE]" , "CIA bar on this Middle East language" , "Middle Eastern language" .)
