Confidence

Formation

First attested
c. 250–184 BC, Plautus
Borrowed from
Ancient Greek βαλανεῖον
Ultimate origin
Ancient Greek (βαλανεῖον)

Pronunciation

  • Classical: [ˈbaɫ.ne.ũː][1]
  • Ecclesiastical: [ˈbal.ne.um][1]

Forms

balneum n (genitive balneī); variously declined, second declension, first declension[1] The older form balineum is the usual one in Plautus and in prose after Augustus.[2] The plural is usually feminine, balneae, but since the Augustan period also neuter, balnea.[2][3] Petronius and inscriptions have a masculine balneus.[3]

Etymology

It is borrowed from Ancient Greek βαλανεῖον (balaneîon, “bath, bathing room”).[3][1][4] Wiktionary notes that it was borrowed early enough for the second ⟨a⟩ to be weakened to ⟨i⟩, giving ⟨balineum⟩, and then lost by syncope.[1]

Earliest recorded meaning

Plautus has “the baths will never take this weariness from me” in the Mercator.[3]

Semantic evolution

It is a bathing room or bathroom, and in the plural a suite of baths or a public bathing establishment;[3][2] Varro holds that the singular was used for a private bath and the plural for public ones, though later writers do not keep to this.[2] It is also the bath itself, the tub for the water, as Seneca's people who drink among the naked almost on the threshold of the bath, and with reference to heating, as Cicero's “I will have the bath heated”.[3][2] It is also the act of bathing, as in Plautus.[3]

Church Latin glosses it “bath”.[5]
