Pronunciation
Forms
orior (present infinitive orī or orīrī, perfect active ortus sum); third (-iō variant) / fourth conjugation, deponent[1] Several present forms follow the third conjugation, as oritur, orerētur.[2][3]
Etymology
It is inherited from Proto-Italic *or-i- (“to rise”), inherited from Proto-Indo-European *h₃r̥-i- (“to rise”), from Proto-Indo-European *h₃er- (“to stir, rise”).[4][1] Cognate with Umbrian ortom est, Sanskrit ऋणोति (ṛṇóti, “rises, moves”) and Ancient Greek ὄρνυμι (órnumi, “to rouse”).[4][2][1]
Earliest recorded meaning
Plautus uses it.[4] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
In Classical Latin it was first used of the sun and stars, to rise above the horizon.[2] It was to get up from bed, as Livy's consul rising in the night, of dust and flames to rise, and of rivers to have their source.[2][6] It was to begin, to come into existence or be born, and to be descended from someone.[2]
Its participle oriēns “rising” became the east, the Orient, and its derivative orīgō “source” gave English origin and original.[7] It survives as Italian orire.[1]
Timeline
- c. 250–184 BC – Plautus uses it.[4][5]
- 59 BC–17 AD – Livy uses it of a consul getting up at night.[8][5]
- late 14th century – English orient is recorded as “the east”.[7]
