What does ingressive mean?
Ingressive means tending to enter, come in, or move inward. Its most common technical use describes signals, data, or traffic arriving at a network, computer system, or other destination; in this sense it is a formal synonym for incoming or inbound. The opposite term is outgoing or egressive. Outside technical writing, ingressive is less frequent but can describe any process or movement directed toward a place or system. Its unusual vocabulary may sound formal or specialized, so ordinary speakers will often prefer incoming for ordinary situations. The word is worth knowing in fields where precise directional terminology distinguishes traffic entering a service from traffic leaving it, especially in networking, telecommunications, and systems administration.
