Sleepy wood? (3)
I believe the answer is:
log
This clue could be a double definition.
'sleepy' is the first definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'wood?' is the second definition.
(log is a kind of wood)
Can you help me to learn more?
(Other definitions for log that I've seen before include "A ship or plane's diary" , "Record book; tree part" , "Lump of wood or ship's diary" , "Official record of events" , "Piece of cut wood" .)
