tutoyer (too-twah-YEY, ty-twa-YEY) - n., to address someone in French using tu and toi; more generally, to address (someone) using a familiar form of the pronoun “you” rather than more formal forms; to address familiarly.
The Spanish equivalent is tutear and a Japanese near-equivalent is yobisute, to address someone without any honorific, but the word we borrowed for straying on the T side of the T-V distinction (itself named from Latin pronouns) is the French one, back in the 1690s. Since English has lost the familiar form thou, this is mostly used in its metaphoric extension.
