Wapan or Jukun Wapan, also known as Wukari after the local town, is a major Jukunoid language of Nigeria.Wapan and other Jukunoid languages are interesting in the development of asymmetrical patterns of nasal and oral consonants in West Africa, where one could posit that voiced oral stops become nasal before nasal vowels, sometimes at the expense of having more nasal than oral vowels (which is typologically odd), or that nasal stops denasalize before oral vowels, which is also typologically odd.
