Confidence
Established
Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Latin (soleō)

Pronunciation

  • Classical: [ĩːˈsɔ.lɪ.tʊs][1]
  • Ecclesiastical: [inˈsɔː.li.tus][1]

Forms

īnsolitus (feminine īnsolita, neuter īnsolitum); first/second-declension adjective[1] It has no comparative or superlative, and a variant īnsul- is recorded.[2]

Etymology

It is formed from in- (“not”) and solitus (“accustomed”), the participle of soleō (“to be accustomed”).[3][2][1][4] The origin of ⟨soleō⟩ is disputed: de Vaan rejects a link with suēscō (“to become used to”) and cites the old proposal adopted by LIV, an iterative Proto-Indo-European *sol-eh₁- (“to occupy, inhabit”).[5]

Earliest recorded meaning

Köbler gives Cicero as its first author,[4] who asks Verres in the Verrines whether he drags farmers from their fields into the forum, to an unfamiliar lawsuit.[3]

Semantic evolution

It is unusual, unfamiliar or unwonted, as in Cicero.[3][6][1] Of people it is unaccustomed to something, used absolutely, with ad or with the genitive, as Cicero's modest women forced to appear, unused and unwilling, before so large a gathering of men.[3][6]

Church Latin glosses it “unaccustomed, unusual”.[7]

Timeline

  • 81–43 BC – Cicero of an unfamiliar lawsuit and of women unused to gatherings.[3][4]

Meanings

Adjective

  1. Unusual, unfamiliar, unwonted.[3][6][1][7]
  2. Unaccustomed (to), unused.[3][6][1][7]

Usage notes

Döderlein notes that solēre is said of events and actions, to be used to happen, while cōnsuēvisse is said only of a person's actions, to be wont.[8]
