Public upset after vase lost (5)
I believe the answer is:
overt
'public' is the definition.
(associated in meaning)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for overt that I've seen before include "Explicit" , "Plainly apparent" , "Clear" , "Trove (anag.)" , "Conspicuous" .)
