Forms

régulier (feminine régulière, masculine plural réguliers, feminine plural régulières)[1] Old French reguler (about 1119), later regulier (1308), with the variant reglier (about 1265).[2][3][4] Popular Old French forms riuler, reuler and rieuler were reshaped after reule, rieule “rule”.[2][5][4]

Etymology

It is inherited from Old French reguler, borrowed from Latin regulāris (“bar-shaped, serving as a rule, canonical”), from rēgula (“rule”) (whence règle).[2][5][6][1] Its first sense renders a meaning that the Latin word took only in Medieval Latin, as a term of calendar reckoning (11th century).[2][5] The suffix -er was replaced by -ier at the beginning of the 14th century, as in bouclier, sanglier and singulier.[2][4][5]

Littré lists Occitan reglar, Spanish regular and Italian regolare.[7]

Earliest recorded meaning

Philippe de Thaon's Comput (about 1119) has jurz regulers, the fixed number of days that, added to a figure varying from year to year, gave the weekday on which each month began.[2][5]

Semantic evolution

Under the influence of règle, the adjective was applied from the early 13th century to what conforms to moral rules, and in the classical period to a person who kept the duties of morality and religion (1671).[2][5] That use has aged, but the related familiar sense “playing fair, keeping the code of honesty” revived it in 1922.[5][2] Already in Old French it took from Church Latin the sense “living under a religious rule” (1174–1176), as opposed to séculier; the noun régulier for a member of such an order is recorded in 1596.[2][5]

From “done in due form” (1552) came the legal sense (1676) and uses in grammar and versification (1690); classical criticism applied it to works written by the rules of the 17th century (1660).[5][2] Soldiers came in with troupes régulières (1751).[2][5]

A second line of meaning moved from “rule” to “steady rhythm”: uniform in time (1270), harmonious in proportions (about 1377 in geometry, 1666 of beauty), recurring at fixed intervals (1808), and habitual rather than occasional (1854).[2][5] In 1930 slang made the feminine noun régulière a man's wife or recognised mistress.[2] In Quebec régulier also means “ordinary”, a calque of the English word regular.[5]
