The Permic languages have traditionally been classified as Finno-Permic languages, along with the Finnic, Saami, Mordvin, and Mari languages. The Finno-Permic and Ugric languages together made up the Finno-Ugric family. However, this taxonomy has more recently been called into question, and the relationship of the Permic languages to other Uralic languages remains uncertain.
Phonology
word roots have been subject to particularly heavy reduction in the Permic languages.
Original geminates *pp, *tt, *kk were reduced to single voiceless stops *p, *t, *k.
Between vowels, original single *p, *t, *k as well as *w and *x were lost entirely.
Second-syllable vowels were lost almost entirely. Certain words in Udmurt may preserve traces.
The sibilants *s, *ś, *š have remained distinct from each other in all positions, but were voiced to *z, *ź, *ž between voiced sounds.
Consonant clusters were largely simplified: in particular nasal + stop/affricate clusters yield voiced stops/affricates, and stop + sibilant clusters yield voiceless sibilants.
A peculiarity of Permic is the occurrence of the voiced consonants such as *b, *g word-initially even in inherited vocabulary, apparently a development from original PU voiceless consonants. The Proto-Permic consonant inventory is reconstructed as: This inventory is retained nearly unchanged in the modern-day Permic languages. Komi has merged original into and undergone a change → or in many dialects, while Udmurt has changed word-initially → or. is retained only in some Udmurt dialects; in other Permic varieties it has become next to back vowels, next to central vowels, next to front vowels. In later Russian loanwords, the consonants can occur. The consonant was marginal and occurred only word-initially or after a word-initial, generally traceable to diphthongization of the close back vowel of the 2nd series. An exceptional word is the numeral "six",, which in Komi is the only native word root with an initial cluster. Literary Komi and literary Udmurt both possess a seven-vowel system. These are however not related straightforwardly, and numerous additional vowels are required for Proto-Permic, perhaps as many as 15 altogether. The reconstruction of Proto-Permic vocalism and its development from Proto-Uralic has always been a puzzling topic, for which there are several models. There is general agreement on the existence of two series of close vowels, one of which results in modern in literary Udmurt and literary Komi-Zyrian, the other in correspondences of Udmurt to Komi . Proposed distinguishing factors for these include length, tenseness and height.
Morphophonology
Noun roots in the Permic languages are predominantly monosyllabic and invariable with the canonical shape VC. CV roots, such as Udmurt ву /vu/, Komi ва /va/ 'water', and VCC roots, such as Udmurt урт /urt/, Komi орт /ort/ 'soul', exist as well. In Udmurt, there are furthermore a number of bisyllabic roots, mostly of the shape VCɨ. In noun roots with certain final clusters, the second consonant surfaces only when followed with a vowel in inflected or derived forms :

Udmurt has similar alternation for a number of other clusters of the shape voiced consonant+/m/, while Komi-Zyrian adds a number of clusters of the shape voiced consonant+/j/. The verb root for 'to come': Udmurt лыкты- /lɨktɨ-/, Komi локты- /loktɨ-/ also shows alternation to plain /k/ in e.g. the imperative.
