In addition to numerous front obstruents, many Northeast Caucasian languages also possess a number of back consonants, including uvulars, pharyngeals, and glottal stops and fricatives. Northeast Caucasian phonology is also notable for its use of numerous secondary articulations as contrastive features. Whereas English consonant classes are divided into voiced and voiceless phonemes, Northeast Caucasian languages are known to contrast voiced, voiceless, ejective and tense phones, which contributes to their large phonemic inventories. Some languages also include palatalization and labialization as contrastive features. Most languages in this family contrast tense and weak consonants. Tense consonants are characterized by the intensiveness of articulation, which naturally leads to a lengthening of these consonants.
