Bill and Ted entertain us on Japanese set (8)
I believe the answer is:
adjusted
'set' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I can't see?
'bill and ted entertain us on japanese' is the wordplay.
'bill' becomes 'ad' (advertisement stuck on wall).
'and' is a charade indicator (letters next to each other).
'entertain' indicates putting letters inside.
'on' is a charade indicator (letters next to each other).
'japanese' becomes 'J' (international code for Japanese vehicles).
'ad'+'ted'='adted'
'us' after 'j' is 'jus'.
'adted' going around 'jus' is 'ADJUSTED'.
Can you help me to learn more?
(Other definitions for adjusted that I've seen before include "Altered slighty for accuracy" , "With small change" , "Altered slightly for accuracy" , "Modified" , "Fixed, adapted or set right" .)
