Forms

regola f (plural regole)[1] Old Italian also wrote regula.[2][3][4]

Etymology

It is borrowed from Latin rēgula (“straight stick, ruler; rule”), a learned or semi-learned word.[5][6][7][1] The Latin noun is formed from regō (“to guide straight, rule”) with a diminutive suffix.[6][1][8] It first meant a straight bar of wood or metal, then a rule of conduct in the moral sense, matching Ancient Greek κανών (kanṓn).[5][9][10]

The popular outcomes of the Latin word kept the concrete sense of a bar: Lombard rega “iron for barrel hoops”, Logudorese “reya” “honeycomb”, Occitan relha “lever”, Spanish reja “grille” and Portuguese relha “ploughshare”.[11][12] The abstract “rule” came back in learned forms: French règle, Spanish regla and Portuguese regra.[11][6][1] English rule comes from Old French rieule.[6]

Several derivatives took their senses from French: regolamento in the sense “ordinance” after French règlement, regolamentare after réglementaire, and regolarizzare after régulariser (1794).[5] The verb regolare seems to be a Romance formation, although a rare Late Latin regulāre existed in the 5th century (Caelius Aurelianus).[5][6]

Earliest recorded meaning

DELI's first record is the rule of a religious order, the norms by which its founder governs the life of the community, before 1292 in Bono Giamboni.[5] GRADIT dates the first record to the second half of the 13th century.[7] Dante uses the word for “measure, manner” (1300–1313): the rain of the third circle of Hell has a “regola e qualità” that never changes.[5][13]

Semantic evolution

The sense “precept, norm of what one should do” is recorded before 1311 in Giordano da Pisa, a norm drawn from experience or custom in 1354 in Iacopo Passavanti, the orderly course of events before 1519 in Leonardo, and a method for solving problems before 1642 in Galileo's “rule of three”.[5] The plural regole “menstruation” is recorded before 1711 in Giovanni Battista Morgagni and is still popular usage.[5][7]

In the lands of the old Venetian Republic, Trentino and Cadore a regola was a rural community holding pastures in common, and Medieval Latin regula had this sense at Padua from the 13th century.[14][15][11] In Tuscany and at Tarquinia in Lazio regola is also the wooden rattle of Holy Week.[16]

Many fixed phrases are built on the word: di regola “as a rule”, in regola “in order”, a regola d'arte “expertly”, avere le carte in regola “to have the right qualifications”, and the proverb l'eccezione conferma la regola.[7][17][10]
