- 81–43 BC, Cicero

- Latin (soleō)
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]

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]
