regularis

Regularis is a Latin adjective meaning "regular" or "according to rule," derived from regula, "rule." In Latin texts, regularis occurs in various phrases and, in scientific naming, can appear as a taxonomic epithet to denote conformity to a standard or pattern.

A notable historical use is the Regularis Concordia, literally "Concord of the Rule." This is a 10th-century English monastic regulation associated with the Benedictine reform movement. The document outlines ideals and practical rules for monastic life, emphasizing obedience, communal governance, liturgical practice, and the organization of monasteries. Its aim was to standardize discipline across English houses and to reaffirm Benedictine observance during a period of reform.

In modern scholarship, regularis mainly appears as a descriptive term within Latin titles or as part of taxonomic epithets, rather than as a standalone concept. The form reflects gender and number in Latin grammar, and in scientific naming it commonly signals regularity, standard characteristics, or conformity attributed to a taxon. Beyond these uses, regularis serves as a linguistic reference point for how Latin adjectives describe conformity to rules or norms in both historical and contemporary contexts.
