Brought to a conclusion everywhere (3,4)
I believe the answer is:

'everywhere' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for all over that I've seen before include "Finished" , "covering everything" , "typically" , "Excessively attentive" , "very characteristically" .)
