virtual
語源
PIE word |

*wiHrós |
The adjective is derived from Middle English vertual, virtual [and other forms],[1] from Old French vertüal, vertüelle (modern French virtuel), or from their etymon Medieval Latin virtuālis (“of または pertaining to potency または power; having power to produce an effect, potent; morally virtuous”), from Latin virtūs (“goodness, virtue; manliness, virility”) (from vir (“adult male, man”) (ultimately from Proto-Indo-European *wiHrós (“man”), possibly from *weyh₁- (“to chase, hunt, pursue”)) + -tūs (suffix forming collective または abstract nouns)) + -ālis (suffix forming adjectives of relationship), modelled after virtuōsus (“good, virtuous”).[2]
Sense 4 (“pertaining to a theoretical infinitesimal velocity in a mechanical system that does not violate the system’s constraints”) is borrowed from French virtuel,[2] from Middle French virtuel, from Old French vertüal, vertüelle: see above.
The noun is derived from the adjective.[2]
