Janet

Janet is an English diminutive of Jane, itself the feminine form of John, which derives from the Hebrew name Yohanan meaning "Yahweh is gracious." The diminutive suffix -et was commonly applied in medieval English and Scottish usage, giving Janet its characteristic form. The name was particularly popular in Scotland, where it long functioned as an independent given name rather than merely a pet form. Related forms include Janette, Janice, and the Scottish variant Jessie, while Jane and Joan are its closer cognates.
