English lad gathers new wood (5)
I believe the answer is:
Here is my best explanation:
'wood' is the definition.
(ebony is a kind of wood)
'english lad gathers new' is the subsidiary indication.
'english' becomes 'e' (abbreviation).
'lad' becomes 'boy' (I've seen this in other clues).
'gathers' indicates putting letters inside.
'new' becomes 'n'.
'boy' placed around 'n' is 'bony'.
(Other definitions for ebony that I've seen before include "Black hardwood", "A hard wood", "Very dark wood", "A hardwood", "Hard dark-coloured wood", "Dark hardwood", "Tree having black wood", "Hard wood used for black piano keys and in cabinetwork", "Heavy hard wood, usually black" and "Hard block tropical wood".)
