For “virtual”, there are several meanings:
virtual
adjective
Definition of virtual
1: being such in essence or effect though not formally recognized or admitted
a virtual dictator
2: being on or simulated on a computer or computer network
print or virtual books
a virtual keyboard
: such as
a: occurring or existing primarily online
virtual shopping
b: of, relating to, or existing within a virtual reality
a virtual tour
3: of, relating to, or using virtual memory
4: of, relating to, or being a hypothetical particle whose existence is inferred from indirect evidence
virtual photons
1 and 2 seem to be conflict. For example, “a virtual teacher”, it could be someone who teaches but is not formally admitted, or a computer-simulating one that teaches.
I can’t distinguish them even there’s context.
