erróneo
/eˈroneo/ · B2 · adj
erroneous
❌📝 erróneo = err (as in 'to err') + -óneo; it's what you get when you err
Spanish erróneo comes from Latin errare, 'to wander, make a mistake', the same root as English err and error. Anything erróneo is the result of erring: a wrong answer, a mistaken idea, or a flawed argument.
