Communicate with bishop over satisfactory primer (8)
I believe the answer is:
textbook
'primer' is the definition.
(I've seen this before)
'communicate with bishop over satisfactory' is the wordplay.
I cannot quite see how this works, but
'bishop' could be 'b' (abbreviation used in chess) and 'b' is present in the answer.
'over' could be 'too' (I've seen this before) and 'too' is present in the remaining letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for textbook that I've seen before include "Volume for school or college" , "Standard reference" , "Reader for student" , "in a perfect way?" , "Student's manual" .)
