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' can be found hidden inside 'sahara bickering'.
'evident' is the 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" .)
