There is dispute whether the –ATR vowels [ɛ], [ɔ], [ɪ], [ʊ] are phonetic variants or separate phonemes.

Fur is written in the Latin alphabet with the addition of the letters a̱ (a with macron below), ɨ, ŋ, and ʉ, and the digraph ny.

In some cases (mostly body parts) it is accompanied by L; e.g.: dɨ́ló"ear"→ kɨ́ló"ears"dɨ́ló → kɨ́ló"ear" {} "ears"nʉ́ŋɨ́"eye"→ kʉ́ŋɨ́"eyes"nʉ́ŋɨ́ → kʉ́ŋɨ́"eye" {} "eyes"dági"tooth"→ kagi"teeth"dági → kagi"tooth" {} "teeth"dormí"nose"→ kormi"noses"dormí → kormi"nose" {} "noses"daulaŋ"shoe"→ kaula"shoes"daulaŋ → kaula"shoe" {} "shoes"dɨróŋ"egg"→ kɨro"eggs"dɨróŋ → kɨro"egg" {} "eggs"nʉ́nʉm"granary"→ kʉ́nʉ́ma"granaries"nʉ́nʉm → kʉ́nʉ́ma"granary" {} "granaries"nʉ́ʉ́m"snake"→ kʉ́ʉ́mɨ́"snakes"nʉ́ʉ́m → kʉ́ʉ́mɨ́"snake" {} "snakes"dɨwwô"new"→ kɨwwóla'wala gal 'kɨwwóŋa"new (PL)"dɨwwô → {kɨwwóla'wala gal 'kɨwwóŋa}"new" {} {"new (PL)"}dewer"porcupine"→ kewértá"porcupines"dewer → kewértá"porcupine" {} "porcupines"da̱wi"tail"→ ka̱wíntó'wala gal ka̱wíntá"tails"da̱wi → {ka̱wíntó'wala gal ka̱wíntá}"tail" {} "tails"úú"cow"→ kuu"cows"úú → kuu"cow" {} "cows"á̱yɨ"which (one)?

Possessives (singular; take k- with plural nouns): The Fur verbal system is quite complicated; verbs fall into a variety of conjugations.

Most adjectives have two syllables, and a geminate middle consonant: e.g. àppa "big", fùkka "red", lecka "sweet".
