Pronunciation

Forms

ordo (feminine orda, masculine plural ordi, feminine plural orde)[1]

Etymology

It is inherited from Latin horridus (“bristling; rough, frightful”).[2][3][4][5][1] The learned doublet of the same Latin word is orrido.[1][3]

Meyer-Lübke explained the vowel of the Tuscan word as taken from lordo, sporco and sordo.[5] Körting notes that the word has a closed /o/, which led Gröber to separate it from the French and Provençal words, but he himself preferred to explain the form by assimilation to lordo.[6] The GDLI and Wiktionary also allow for the influence of that word.[4][1]

The same Latin adjective gave Old French ort, feminine orde, with the noun ordure, still French ordure today, and Old Occitan ort.[6] Meyer-Lübke adds Aretine ordio (“rough, bad”) and an Old Lombard orrio.[5] The Latin adjective comes from horreō (“to bristle, shudder”) with the suffix -idus.[7][1] De Vaan traces the verb to Proto-Italic *χors-ē- (“to be stiff”) and further to Proto-Indo-European *ǵʰr̥s-éh₁- (“to be stiff, surprised”).[8]

Earliest recorded meaning

GRADIT dates the adjective to the 13th century.[2] Among the GDLI's earliest quotations is the Proverbia super natura feminarum, where a dyed colour is called una color bruta, orda e vilana (“an ugly colour, filthy and base”), in the literal sense “dirty, foul”.[4]

Semantic evolution

In Old Italian the adjective meant “dirty, unwashed”: a vernacular Seneca warns against making oneself conspicuous by being ordo, mal pettinato (“dirty, badly combed”).[4] It was soon used of the mind: Guittone writes of gli ordi di cuore (“the foul of heart”), a translation of the Lord's Prayer asks the reader to put away all thoughts carnali e ordi e mondani (“carnal, foul and worldly”), and the Proverbia call a joke orda, that is, unseemly.[4][9]

It could also mean “ugly, deformed”: Giovanni Villani tells of a woman who gave birth to la più orda e orribile creatura (“the foulest and most horrible creature”).[4][9] Tommaseo already marked the word as obsolete and compared French ordure.[9] Modern dictionaries list it only as an obsolete or rare word.[2][3][1]

Timeline

  • 1200s – GRADIT's date for the first record of the adjective.[2]
  • Before 1348 – The date Zingarelli gives for the word.[3]
  • 1861 – Tommaseo–Bellini marks it as obsolete.[9]

Usage notes

Tommaseo notes that the adjective was pronounced with a closed /o/, like lordo.[9]

Old Italian also had a rare learned noun ordo “order”, a synonym of ordine taken from Latin ōrdō, which the GDLI quotes from the verse of Nuccoli and Cicerchia.[4][1]
