Something or someone that exists; a being or entity that has existence (rare or archaic term).
From exist (Latin existere) with the agent suffix -er (one who). This term is archaic and rarely used in modern English, largely replaced by 'being' or 'entity.'
This is a beautifully simple word that just means 'something that exists'—but it's so old-fashioned that almost no one uses it anymore. It shows how English speakers once tried to make a noun for 'a thing that exists!'
