Janette is a variant of the name Janet, which itself is a diminutive form of Jane. Jane originates from the Old French name Jehanne, which is derived from the Latin name Iohanna, a feminine form of Iohannes. The name Iohannes comes from the Greek name Ioannes, which is derived from the Hebrew name Yochanan, meaning 'Yahweh is gracious.' Janette, therefore, carries the same meaning, symbolizing grace and divine favor.
