Pronunciation

  • /ˈre.ɡu.lə/[1]

Forms

regulă f (plural reguli)[1] MDA2 records the old variants regolă and regură, răgulă (regional) and the old plural regule.[2] The Lexicon de la Buda of 1825 spells it regulă in its Latinist orthography and glosses it with Latin regula, norma, lex.[3]

Etymology

It is borrowed from Latin rēgula (“straight stick, ruler; rule”), a learned borrowing, with Italian regola as a further model and some senses after French règle.[4][1][5] MDA2 names Latin and French, and DN Latin with the Italian and French words beside it.[2][6] The Latin noun is formed from regō (“to rule, guide”) with the diminutive suffix -ula.[1]

Ciorănescu dates the borrowing to the 19th century; the form is older.[7][5] The same Latin word reached Romanian earlier through Greek as riglă “ruler”, from Modern Greek ρίγλα (rígla), so the two are doublets.[7][1] Dosoftei used a form răgulă for an order or class, perhaps a Latinism.[7]

Earliest recorded meaning

Tiktin and MDA2 take the first record from Foletul novei, the calendar kept at Constantin Brâncoveanu's court;[3] Tiktin dates the entry to 1703, while MDA2's 1693 is the first year of the calendar.[5][2] The sense was a rule or norm.[5]

Semantic evolution

The Lexicon de la Buda (1825) gives three senses: a rule or law, a habit, and a person's or horse's whim.[3] In the 19th century the word took the arithmetical sense of an operation, as in regula de trei “the rule of three”, and Costinescu also records it for menstruation.[8] That popular sense survives in DEX.[4]

The noun gave the verb regula “to regulate, put in order”, which later took coarse slang senses.[7] Fixed phrases include de regulă “as a rule” and în regulă “all right, in order”.[4]

Timeline

  • 1703 – in Foletul novei, the first record.[5][2]
  • 1825 – regulă in the Lexicon de la Buda.[3]
  • 1870 – Cihac lists it with the verb regulez.[9]
  • 1870 – the rules of arithmetic and the sense “menstruation” in Costinescu.[8]
