Animal eats rook and chicken part (6)
I believe the answer is:
breast
'chicken part' is the definition.
('breast' is part of 'chicken')
'animal eats rook' is the wordplay.
I cannot really see how this works, but
an anagram of 'eats' is 'east' which is present in the answer.
'rook' could be 'r' (chess abbreviation) and 'r' is found within the answer.
A single letter 'b' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for breast that I've seen before include "Milk supplier" , "Get on top" , "Outer thorax" , "Cut of chicken" , "Manfully oppose" .)
