Pronunciation

  • Classical: [ˈruːk.toː], [ˈrʊk.toː][1]
  • Ecclesiastical: [ˈruk.to][1]

Forms

rū̆ctō (present infinitive rū̆ctāre, perfect active rū̆ctāvī, supine rū̆ctātum); first conjugation[1] A deponent form ructor is used by Varro and Horace.[2][3]

Etymology

It is from Latin *rūgō (“to belch”) + -tō, a frequentative formed on the stem of a simple verb that is not attested on its own.[2][1] Its compound ērūgō (“to belch”) is found from Ennius on, and the noun ructus (“belch”) from Plautus.[4] De Vaan traces the root to Proto-Italic *roug-e/o- and Proto-Indo-European *h₁reuǵ-e/o- (“to belch”).[4]

Cognate with Ancient Greek ἐρεύγομαι (ereúgomai, “to belch out, vomit”), Lithuanian ráugėti (“to belch”) and Old English rocettan (“to belch”).[4][1]

Earliest recorded meaning

De Vaan records it from Plautus on.[4] In the Pseudolus one character asks another, pergin ructare in os mihi?, “will you keep belching in my face?”.[5][3]

Semantic evolution

Used intransitively it means simply to belch: Cicero speaks of a man for whom even belching would be shameful, and Pliny the Elder of someone who never spat or belched.[3][6] With an object it names the food or drink whose taste or fumes come back up: Varro, using the deponent, says he still “belches” someone's birds, and Pliny the Elder has a stomach that “belches” sour things.[3][6]

From this it came to mean bringing something up with a belch: Silius Italicus has blood belched from a lion's throat, and both he and Statius use it of natural forces, a river or fire that belches out what it carries.[2] Horace mocks a poet who “belches out” lofty verses,[2][3] and later writers use it scornfully of words that are always in someone's mouth: Tertullian of displayed wisdom, Sidonius Apollinaris of a man who “belches the Tiber”, that is, speaks polished Roman Latin.[3][6][5] Palladius uses it of the earth giving off vapour.[3][6]
