Fellow trimmed representation of coral in black-and-white drawing (8)
I believe the answer is:
charcoal
'black-and-white drawing' is the definition.
'charcoal' can be an answer for 'drawing' (charcoal is a kind of drawing). I'm not sure about the 'black-and-white' bit.
'fellow trimmed representation of coral' is the wordplay.
'fellow' becomes 'chap' (both can mean a man).
'trimmed' means to remove the last letter (the last letter is trimmed off).
'representation of' indicates anagramming the letters (I've seen this in other clues).
'chap' with its last letter removed is 'cha'.
'coral' with letters rearranged gives 'rcoal'.
'cha'+'rcoal'='CHARCOAL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for charcoal that I've seen before include "Kind of fuel made by burning wood" , "Black stuff for burning or drawing" , "Standard" , "Black residue of burnt wood" , "It's made by burners for use in burners" .)
