Word Origin and History for viciously

vicious

adj.

early 14c. (implied in viciously), "of the nature of vice, wicked," from Anglo-French vicious, Old French vicieus, from Latin vitiosus "faulty, defective, corrupt," from vitium "fault" (see vice (n.1)). Meaning "inclined to be savage or dangerous" is first recorded 1711 (originally of animals, especially horses); that of "full of spite, bitter, severe" is from 1825. In law, "marred by some inherent fault" (late 14c.), hence also this sense in logic (c.1600); cf. vicious circle in reasoning (c.1792, Latin circulus vitiosus), which was given a general sense of "a situation in which action and reaction intensify one another" by 1839.
