Sort of saw for cutting a joint? (5)
I believe the answer is:
tenon
'joint?' is the definition.
(I've seen this in other clues)
'sort of saw for cutting a' is the wordplay.
'sort of saw for' becomes 'ten' (I can't justify this - if you can you should give a lot more credence to this answer).
'cutting' means to remove the last letter.
'a' becomes 'one'.
'one' with its final letter taken away is 'on'.
'ten'+'on'='TENON'
Can you help me to learn more?
(Other definitions for tenon that I've seen before include "Piece of wood that fits into a mortise" , "Piece of wood fitting into a mortice" , "Mortise counterpart" , "Wooden projection shaped to fit in a mortise joint" , "One projecting" .)
