Forms

Etymology

It is borrowed from Ancient Greek ἰδιώτης (idiṓtēs, “private person, layman”),[2][3][1] from ἴδιος (ídios, “one's own, private”).[1][4] Isidore of Seville explains it as an unskilled person, and the glossaries render it as prīvātus and indoctus.[5]

Earliest recorded meaning

Its first author is Lucilius, in the late 2nd century BC,[6][5] who complains that someone might call him “unlettered and a layman”.[2][7]

Semantic evolution

It meant an ordinary person as opposed to an expert, a layman or amateur, and Cicero uses it of those whom a connoisseur of art looks down on as ignorant.[2][7] Seneca the Elder has it for a private individual holding no public office, its Greek sense.[2] Quintilian uses idiotae for the common crowd.[7]

In Late and Medieval Latin it meant an ignorant or illiterate person, a recent convert, a lay brother, and a private person.[8][1] Through Old French it gave English idiot in the early 14th century.[4]
