Forms
irrégulier (feminine irrégulière, masculine plural irréguliers, feminine plural irrégulières)[1] Old French irreguler (about 1283); irrégulier from the early 14th century.[2][3]
Etymology
It is borrowed from Late Latin irrēgulāris (“not conforming to the rule”), a word of Christian Latin, formed from in- and rēgulāris (“serving as a rule”), from rēgula (“rule”).[4][3][2] The TLFi divides it: the general sense “not following the rules” is treated as a derivative of régulier with the negative prefix, after the Latin word, while the canon-law sense, applied to a cleric who cannot be ordained, is the Latin word borrowed, with its ending replaced by -ier.[5][6]
Cognate with Old Occitan irregular, Spanish irregular and Italian irregolare.[7]
Earliest recorded meaning
Beaumanoir's Coutumes de Beauvaisis (1283) uses irreguler of people who do not keep the rules: those who handed over criminals disguised as clerics seroient irreguler.[5][7]
Semantic evolution
In canon law it was used before 1300 of an abbot unfit for his office.[5] Before 1382 Oresme applied it to things that do not conform to a rule, and in the 14th century it was used in grammar.[5][2] Molière speaks of an irregular procedure in 1659;[5] vie irrégulière “a disorderly life” is recorded in 1671 and an irregular building in 1680.[5] Montaigne (1580) uses it for what is uneven in form, and in 1763 Voltaire writes of troupes irrégulières outside the regular army.[2][5] In the 19th century irréguliers also named native troops serving with the French army in Algeria.[7]
