A rare or archaic term for an occurrence or instance; a matter or affair that has taken place.
From Latin ex- (out) + stans (standing, from stare 'to stand'). The word literally refers to something that 'stands out' or has occurred, an event of note.
This word is so archaic that even English dictionaries barely mention it—it's the linguistic equivalent of an archaeological artifact, barely used even in Shakespeare's time.
