Fur has 21 consonant phonemes including the distinctive prenasalized stops mb, nd, and ŋg — each a single phoneme, not a cluster. The labio-velar stop kp (produced simultaneously at both lips and back of mouth) is unusual in sub-Saharan languages outside West Africa. Affricates and the full range of nasals complete the consonant inventory [1].
Fur has five vowel qualities (a, e, i, o, u), each occurring in short and long forms — giving 10 vowel phonemes. Vowel length is phonemically contrastive. Fur also has three contrastive tone levels (high, mid, low), making it one of the few Nilo-Saharan languages with a three-way tonal distinction. Tone is not marked in the standard written orthography [1].
Fur numeral words reflect the language's phonological features. The word for nine (ndúgùl) begins with the prenasalized stop nd — showing that these complex segments appear in core vocabulary. Tonal diacritics (when marked) show the three-tone contrast [1].
The complete Fur Latin alphabet. Fur's writing system uses standard Latin characters plus the digraphs kp, mb, nd, ŋg for the prenasalized and labio-velar consonants. Doubled vowel letters represent long vowels. The historical importance of the Fur language in the Darfur Sultanate gives it unique cultural significance in Sudanese history [2].
The Fur people of Darfur are predominantly Muslim, and Ajami writing — using Arabic script for non-Arabic languages — was used in the Darfur Sultanate (1603–1916) for religious texts and correspondence. Most Fur consonants map to standard Arabic letters; the labio-velar kp and prenasalized stops mb, nd, ŋg required multi-letter approximations in Ajami writing, as Arabic script has no single letters for these Nilo-Saharan sounds [1].
