emergent

1. (especially medicine) Constituting an emergency.Examples: "Therefore, patients with ulcerative colitis should ideally be treated before they become emergent cases with toxic megacolon or perforation of the colon."; "Bleeding manifestations in chronic DIC are more subacute than in acute DIC, but may become emergent as DIC progresses."; "As a rule, esophageal disorders become emergent when the airway is compromised either by the initial insult or by a high risk of aspiration."especially

2. (botany) Taller than the surrounding vegetation.

3. (botany, of a water-dwelling plant) Having leaves and flowers above the water.

4. (video games) Having gameplay that arises from its mechanics, rather than a linear storyline.Examples: "In short, emergent games are ones that allow a huge range of possibilities and don't dictate a strict, linear flow of events. A strategy game is emergent because so many units can interact and have some effect on each other."

5. (philosophy, epistemology, sciences) That arises at a higher level than that of its components and is not explainable by the behaviour of said components taken individually; having properties as a whole that are more complex than the properties contributed by each of the components individually.Examples: "an emergent property"; "A high-level phenomenon is strongly emergent with respect to a low-level domain when the high-level phenomenon arises from the low-level domain, but truths concerning that phenomenon are not deducible even in principle from truths in the low-level domain.[…] A high-level phenomenon is weakly emergent with respect to a low-level domain when the high-level phenomenon arises from the low-level domain, but truths concerning that phenomenon are unexpected given the principles governing the low-level domain."
