Hot drink taken by king in wood (4)
I believe the answer is:
teak
'wood' is the definition.
(type of timber)
'hot drink taken by king' is the wordplay.
'hot drink' becomes 'tea' (I've seen this before).
'taken by' is a charade indicator (letters next to each other).
'king' becomes 'k' (chess abbreviation).
'tea'+'k'='TEAK'
'in' is the link.
(Other definitions for teak that I've seen before include "Valuable, dense wood" , "Take away with very hard wood" , "Hardwood tree" , "Hard wood for Kate" , "Heavy wood of a tall evergreen Asian tree" .)
