Shock agreement from German, right? (3)
I believe the answer is:
jar
'shock' is the definition.
(both can mean to shake)
'agreement from german right?' is the wordplay.
'agreement from german' becomes 'j' (I can't explain this - if you can you should believe this answer much more).
'right?' becomes 'ar' (I've seen this in other clues).
'j'+'ar'='JAR'
Can you help me to learn more?
(Other definitions for jar that I've seen before include "Wide-mouthed vessel" , "Disturbing effect" , "Grate" , "Shock; container" , "drink" .)
