virtual🔊

In effect or essence, rather than in fact or reality; also, imitated, simulated.

For practical purposes, though not technically; almost complete, very near.

(computing)

Operating using a computer and/or online rather than physically present.

Simulated in a computer and/or online.

(OOP)(object-oriented programming) Of a class member: capable of being overridden with a different implementation in a subclass.

(mechanics)(mechanics) Pertaining to a theoretical infinitesimal velocity in a mechanical system that does not violate the system's constraints; also, of other physical quantities: resulting from such a velocity.

(physics)

Pertaining to a theoretical quality of something which would produce an observable effect if counteracting factors such as friction are disregarded; specifically, of a head of water: producing a certain pressure if friction, etc., is disregarded.

(optics) ''Chiefly in'' virtual focus: of a focus or point: from which light or other radiation apparently emanates; also, of an image: produced by light that appears to diverge from a point beyond the reflecting or refracting surface.

(particle physics) Pertaining to particles in temporary existence due to the Heisenberg uncertainty principle.

(quantum mechanics) Of a quantum state: having an intermediate, short-lived, and unobservable nature.

(obsolete)

Having efficacy or power due to some natural qualities.

# (figuratively) Of a plant or other thing: having strong healing powers; virtuous.

Having the power of acting without the agency of some material or measurable thing; possessing invisible efficacy.

Producing, or able to produce, some result; effective, efficacious.

(t=full of virtue; having excellent moral character).

''Preceded by'' the: that which is imitated or simulated rather than existing in fact or reality; an instance of this.

That which is simulated in a computer and/or online; virtual reality; an instance of this; specifically (gambling), a computer simulation of a real-world sport such as horse racing.

(programming) A virtual ''(adjective (OOP))'' member function of a class.
