/ɪn ˈɛse/ – Phrase
Definition: Tồn tại.
A more thorough explanation: a Latin Phrase meaning in existence, used to describe a child after it is born. The term contrasts with in posse (=potential; not yet existing), and can also be used to describe anything that exists, or anything that is real.
Example: The estate was granted to the five children in esse, but not the one child in posse.
