fem. proper name, from Latin, fem. of Priscillus, diminutive of Priscus (fem. Prisca), from priscus "antique, ancient, of old; old-fashioned, primitive, venerable," from *pris-ko-, adjective from *pris-, *pri "before," probably from PIE root *per- (1) "forward," hence "in front of, before, first."
In England, the name replaced native Weodmonað "weed month." Traditionally the first month of autumn in Great Britain, the last of summer in the U.S.
German equivalent of Mister (but also used without a name), 1650s, originally "nobler, superior," from Middle High German herre, from Old High German herro, comparative of hēr "noble, worthy, important, exalted," from PIE *kei- (2), a color adjective (see hue (n.1)), in suffixed form *koi-ro- here meaning "gray, hoary," hence "gray-haired, venerable." Cognate with Old Frisian hera, Dutch heer; perhaps in this usage a loan-translation of Latin senior in the High German area that spread into other Germanic languages. Hence also Herrenvolk "master race," the concept of the German people in Nazi ideology.
