Section of Wood’s diary? (3)
I believe the answer is:
log
This clue could be a double definition.
'section of wood's' is the first definition.
'log' can be an answer for 'wood's' (a log is a piece of wood). I am not sure about the 'section of' bit.
'diary?' is the second definition.
(log can mean a record or diary)
Can you help me to learn more?
(Other definitions for log that I've seen before include "Record kept" , "Listing" , "Chunk of wood" , "number in mathematical table" , "A ship's journal" .)
