Etymology
Origin of vitiate
First recorded in 1525–35; from Latin vitiātus, past participle of vitiāre “to spoil, impair,” derivative of vitium “blemish, defect, fault” + -ātus; see vice 1, -ate 1
Explanation
As some sneaky five-year-olds know, crossing one’s fingers while making a promise is an effective way to vitiate, or destroy the validity of, an agreement. Vitiate is often used when a legal agreement is made invalid, but it can also refer to the debasement or corruption of something or someone. If a malicious five-year-old on the playground teaches the other children to lie with their fingers crossed, she would be responsible for vitiating the playground community. The first syllable of this word is pronounced "vish," like the first syllable in vicious.
