Pronunciation

  • Classical: [au̯sˈkʊɫ.toː][1]
  • Ecclesiastical: [au̯sˈkul.to][1]

Forms

auscultō (present infinitive auscultāre, perfect active auscultāvī, supine auscultātum); first conjugation[1] A Pompeian inscription has obscultat.[2] Charisius records a deponent auscultor.[3]

Etymology

It is probably inherited from Proto-Italic *auskoltā, a compound whose first part is the old unrhotacized stem *aus- of auris (“ear”).[1][4][3] De Vaan traces auris to Proto-Italic *aus(i)- and Proto-Indo-European *h₂eus- (“ear”).[4] The second part is often explained as a form meaning hearing, from Proto-Indo-European *ḱlew- (“to hear”), the root of clueō (“to be called”);[4][2][1] Klingenschmitt reconstructs *h₂eus-ḱlut-eh₂-ie/o-, with metathesis to ⟨-cult-⟩.[4][2][1] Others take the second part from *ḱel- (“to incline”).[1][5] Cognate with the words for ear Old Irish áu, Ancient Greek οὖς (oûs) and Lithuanian ausìs.[4]

Earliest recorded meaning

De Vaan dates it from Plautus,[4] whose Casina has someone told where to listen.[2]

Semantic evolution

It means to listen or listen to, and to give heed or obey: a character in Caecilius says he usually hears strangers when they give orders, but does not obey them.[2] It also means to listen secretly, overhear, as in Plautus' “I heard all that from the door”.[2] Döderlein distinguishes it from audiō, mere hearing: it is to wish to hear, to hearken attentively.[6] Lewis & Short note that it is very frequent before the classical period, but rare in it.[7] Church Latin glosses it to listen.[8] English auscultate (1832) is from its participle, and English scout may go back to it through Old French escouter.[5]

  • c. 250–184 BC – Plautus of listening and overhearing.[2][9]
  • 230/220–168 BC – Caecilius of obeying orders.[2][9]
  • 1832 – English auscultate is formed from its participle.[5]
