Take in some Arabs or Berbers (6)
I believe the answer is:
absorb
'take in' is the definition.
('absorb' can be a synonym of 'take in')
'some arabs or berbers' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ABSORB' is hidden in the letters of 'arabs or berbers'.
(Other definitions for absorb that I've seen before include "Take in, soak up." , "Take in, water or knowledge" , "Assimilate, ingest" , "Become imbued" , "Take in and digest, food or knowledge" .)
