Reviews a couple of articles by a bishop for the primate to take in (6)
I believe the answer is:
banana
'for the primate to take in' is the definition.
'reviews a couple of articles by a bishop' is the wordplay.
'a couple of articles' can mean two substitutions for 'articles'.
'reviews' says the letters should be written backwards (view the letters another way).
'articles' says to put letters next to each other.
'articles' becomes 'anan' (two examples of the part-of-speech: an+an**).
'by' means one lot of letters go next to another.
'bishop' becomes 'b' (abbreviation used in chess).
'anan'+'a'='anana'
'anana'+'b' is 'ananab'.
'ananab' back-to-front is 'BANANA'.
(Other definitions for banana that I've seen before include "Curved yellow fruit" , "One out of hand" , "Elongated edible fruit" , "Tropical yellow fruit" , "Fruit that comes in a bunch" .)
