Take in a small circle, including bishop (6)
I believe the answer is:
absorb
'take in' is the definition.
(synonyms)
'a small circle including bishop' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'circle' becomes 'orb' (I've seen this in another clue).
'including' means one lot of letters goes inside another.
'bishop' becomes 'B' (chess abbreviation).
'a'+'s'+'orb'='asorb'
'asorb' placed around 'b' is 'ABSORB'.
(Other definitions for absorb that I've seen before include "Carved figure" , "Grip" , "Soak up - engross" , "Draw in, knowledge or food" , "Take or drink in" .)
