Stretcher in match forbidden, did you say? (6,4)
I believe the answer is:
rubber band
'stretcher' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'match forbidden did you say?' is the wordplay.
'match' becomes 'rubber' (I've seen this before).
'forbidden' becomes 'banned' (banning is a kind of forbidding).
'did you say?' shows a homophone (sound like).
'banned' is a homophone of 'band'.
'rubber'+'band'='RUBBER BAND'
'in' is the link.
Can you help me to learn more?
(Other definitions for rubber band that I've seen before include "Stretchy fastener" , "Elastic item" , "use it to hold things together" , "Office item" , "that should fit tightly" .)
