Timber well suited as a sleeper? (3)
I believe the answer is:
log
'timber' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for log that I've seen before include "number in maths class?" , "Official record of events" , "Piece of wood for the fire" , "Record book; tree part" , "Ship's record" .)
