Regula

Frau Regel Amrain und ihr Jüngster (Mrs. Regel Amrain and her youngest [son]) is a story by the famous Swiss author Gottfried Keller, first published in 1856. Regel is an old-fashioned version of Regula. Swiss short forms are Rägi, Rägle, Rägele, Rägeli (the a-Umlaut sound is more or less similar to the vowel in the word cash).

Although Regula is indeed the feminine version of Regulus, the early Christian context in which the name first appeared makes the meaning "rule", "ruler" (in the sense of measuring device) much more plausible. Most bearers of the name are either Swiss or of Swiss decent, to be precise, from the Zuerich area, from Chur in the canton of Graubuenden or, more rarely, from Andermatt in the canton of Uri where the relics of the Zurich town saint were brought during the Reformation.

This is the Latin word for rule.
