What is the origin of infatuated?


When we speak of someone being infatuated it very often is in relationship to that person having seemingly taken leave of his or her senses, especially in a romantic context (“he was so infatuated that he could not remember what day of the week it was”). This is fitting, as the word shares an origin with the word fatuous, which means complacently or inanely foolish. Both words come from the Latin fatuus (“foolish”), although fatuous is not often used in the romantic contexts in which we find infatuate. When used with a preposition infatuated is typically followed by with.
