idiot: idiot: [13] The etymological idea underlying idiot is of a ‘private individual’. That is what Greek idiótēs (a derivative of ídios ‘personal, private’) originally meant. It was extended to the ordinary ‘common man’, particularly a lay person without any specialized knowledge, and so came to be used rather patronizingly for an ‘ignorant person’. It is this derogatory sense that has come down to English via Latin idiōta and Old French idiot.
=> idiosyncracy
idiot (n.): early 14c., "person so mentally deficient as to be incapable of ordinary reasoning;" also in Middle English "simple man, uneducated person, layman" (late 14c.), from Old French idiote "uneducated or ignorant person" (12c.), from Latin idiota "ordinary person, layman; outsider," in Late Latin "uneducated or ignorant person," from Greek idiotes "layman, person lacking professional skill" (opposed to writer, soldier, skilled workman), literally "private person (as opposed to one taking part in public affairs)," used patronizingly for "ignorant person," from idios "one's own" (see idiom).
