Forms

ōrdinātus (feminine ōrdināta, neuter ōrdinātum, comparative ōrdinātior, superlative ōrdinātissimus); first/second-declension adjective[1][2]

Etymology

Used as an adjective, it is the perfect participle from Latin ōrdinō (“to arrange, put in order”).[1][3] De Vaan explains that verb as a later denominative of ōrdō (“row, order”), made when the link between the noun and its older denominative ōrnō (“to adorn”) had become opaque; for the noun he gives Proto-Italic *ord-n- (“row, order”) and, with a query, Proto-Indo-European *h2or-d-.[4]

Earliest recorded meaning

The earliest example in the OLD is in Livy (59 BC–AD 17), who contrasts a disorderly flight with an orderly march.[1][5] Georges cites it also from Cicero and Nepos.[2]

Semantic evolution

It means well ordered or regulated: Valerius Maximus has a city well ordered by its customs and laws, and Seneca the upper part of the world, more ordered than the lower, and a mind most ordered, sound and calm.[1][3] Of movement it means orderly or regular: Apuleius uses the superlative of the courses of the planets, and Celsus of a naturally regular pulse.[1] The land surveyors use it in geometry, with the dative, for lines that are parallel.[1][3]

Usage notes

Medieval Latin also has nouns spelled ordinatus: Niermeyer records one of the second declension meaning a proxy and one of the fourth declension meaning furniture,[6] and British sources have a fourth-declension noun for the arrangement or disposition of things, as of ships around 1193.[7]
