Nine

Nine is a Frisian and Dutch feminine given name, functioning as a short form of names ending in -nine or -nien, most commonly Antonina or Janine, following a widespread Low German and Frisian tradition of forming pet forms from the final syllable of longer names. It has been used in the Netherlands and Frisian-speaking regions of Germany as an independent given name since at least the nineteenth century. Related forms include Nina, Nien, and Nienke.
