Pronunciation

  • Classical: [kõːˈfuː.si.oː][1]
  • Ecclesiastical: [koɱˈfuː.s̬i.o][1]

Forms

cōnfūsiō f (genitive cōnfūsiōnis); third declension[1]

Etymology

It is from Latin cōnfundō (“to pour together, mix, confuse”) + -tiō.[2][1][3] De Vaan lists cōnfundō under fundō “to pour”, which he traces to Proto-Italic *χund- and Proto-Indo-European *ǵʰu-n-d- (“to pour”), comparing Ancient Greek χέω (khéō, “to pour”).[4]

Earliest recorded meaning

The TLL and Köbler find it first in Cicero,[3][5] who speaks of a combining of parts.[2]

Semantic evolution

It is a mixing or blending and the mixture produced: Seneca says a river is kept from mingling with worse water, and calls the rainbow a mixture of many images of the sun.[2] Ōris cōnfūsiō is a blush: Tacitus has frequent blushing taken for modesty.[2] Cicero uses it of the union of the virtues, which philosophers distinguish by reason.[2] It is also disorder: Cicero writes of such disturbance and confusion of affairs.[2] Of the mind it is consternation: Velleius asks what alarm there was in the senate and what consternation among the people.[2] In grammar Terentianus Maurus uses it of crasis, and in law it is the merging of a right in another, as when the holder of a usufruct acquires ownership.[2] In Church and medieval Latin it is shame, confusion.[6][7]
