Shape a wooden seat (4)
I believe the answer is:
form
This could be a double definition.
'shape' is the first definition.
(I know that shape can be written as form)
'a wooden seat' is the second definition.
'form' can be an answer for 'seat' (I've seen this before). I am unsure of the 'a wooden' bit.
Can you help me to learn more?
(Other definitions for form that I've seen before include "Part of school" , "Criminal record (colloq.)" , "Printed document with blank spaces for information to be inserted" , "Printed document with spaces to write" , "Acceptable conduct" .)
