Would sound like something you saw (4)
I believe the answer is:
wood
'something you saw' is the definition.
I can't tell whether this defines the answer.
'would sound' is the wordplay.
'sound' indicates a 'sounds like' (homophone) clue.
'would' sounds like 'WOOD'.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for wood that I've seen before include "Lots of trees" , "Concert promoter" , "Kind of musical instrument" , "Grove" , "Revered Proms character" .)
