Somewhat shocking piece of pottery? (3)
I believe the answer is:
jar
'pottery?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'somewhat shocking piece' is the wordplay.
'somewhat shocking' becomes 'ja' (I am not sure about this - if you are sure you should believe this answer much more).
'piece' becomes 'r' (abbreviation for Rook).
'ja'+'r'='JAR'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for jar that I've seen before include "Jolt with glass container" , "Shock; container" , "Grate" , "Disturbing effect" , "Pint glass of beer, perhaps" .)
