## AI Etymology
Regularity comes from regular + -ity, ultimately from Latin regularis ('according to rule'), from regula ('rule, straight stick'), from regere ('to rule, keep straight'). The historical chain includes Latin regularis, Latin regula, and Latin regere. The quoted older senses, "according to rule", "rule, straight stick", and "to rule, keep straight", supply the semantic anchors for regularity. The formation is best read as suffixal and borrowed: the word regularity carries its older form-history into a compact English lexical shape. In present English it is used as a noun, "the quality of being even, consistent, or recurring". Related English forms include regular, regulate, regularly, and rule. The result is a noun whose etymology preserves both the older form and the later English specialization.
