Scrambled Into van. No one returned with a new device (10)
I believe the answer is:
innovation
'a new device' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'scrambled into van no one returned' is the wordplay.
'scrambled' indicates anagramming the letters.
'one' becomes 'i' (Roman numeral).
'returned' says the letters should be written in reverse.
'no'+'i'='noi'
'noi' back-to-front is 'ion'.
'into'+'van'='intovan'
'intovan' is an anagram of 'innovat'.
'innovat'+'ion'='INNOVATION'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for innovation that I've seen before include "Something new" , "What's new" , "New idea" , "Something introduced as a novelty" , "New product" .)
