Daily column includes a drawing (8)
I believe the answer is:
charcoal
'drawing' is the definition.
(charcoal is a kind of drawing)
'daily column includes a' is the wordplay.
'daily' becomes 'char' (I've seen this before).
'column' becomes 'col'.
'includes' means one lot of letters goes inside another.
'col' going around 'a' is 'coal'.
'char'+'coal'='CHARCOAL'
(Other definitions for charcoal that I've seen before include "Black carbon from burnt wood" , "Fuel - stick for drawing" , "Black fuel made from wood, good for barbecues (8)" , "coloured sticks" , "Sort of grey" .)
