Pronunciation

  • Classical: [kɔmˈmuː.toː][1]
  • Ecclesiastical: [komˈmuː.to][1]

Forms

commūtō (present infinitive commūtāre, perfect active commūtāvī, supine commūtātum); first conjugation[1]

Etymology

It is formed from Latin con- + mūtō (“to change, exchange”).[2][1][3] De Vaan explains ⟨mūtō⟩ from a noun Proto-Italic *moito- (“object of exchange”), also behind mūtuus (“lent, mutual”), and gives two possible sources, Proto-Indo-European *moyth₂-o- from the root of mittō or another root for “to exchange”.[4]

Earliest recorded meaning

De Vaan gives Plautus as its first author.[4] In the Mercator a father asks his son why his colour has changed.[2]

Semantic evolution

It is to change more or less completely, a road or a drain in a law, a person's fortune (an old tragic poem), one's course, as Cicero's sailor who changes course to reach port, and a person's outlook.[2][5] In Plautus it is to change for the worse, to replace, as a name, and to move one's home, Cato uses it of moving oil dregs from vat to vat.[2] It is also to exchange, barter, as Cicero's exchange of books, verba commūtāre to exchange words, and to transform, as Plautus' Mercury, “I am a god, I will change it”.[2][1]

Church Latin glosses it “change, substitute”.[6] English commute (mid-15th century) first meant to change one thing into another.[3]
