I vote against including large item of decorative woodwork? (5)
I believe the answer is:
inlay
'decorative woodwork?' is the definition.
(I've seen this in another clue)
'i vote against including large' is the wordplay.
'vote' becomes 'nay' (I've seen this in another clue).
'against' means one lot of letters go next to another.
'including' is an insertion indicator.
'large' becomes 'L' (eg in clothes sizes).
'i'+'nay'='inay'
'inay' enclosing 'l' is 'INLAY'.
'item of' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for inlay that I've seen before include "Mix images" , "Insert wood, stone or metal into a surface" , "Embed" , "Decorate by embedding" , "Decoration of a surface by inserting wood, stone or metal" .)
