The following multigraphs are used in the Cyrillic script. The palatalized consonants of Russian and other languages written as C-⟨ь⟩ are mostly predictable and therefore not included here unless they are irregular. Likewise, in the languages of the Caucasus, there are numerous other predictable multigraphs that are not included. These include doubled letters (or whole digraphs) that indicate 'tense' ('strong') consonants and long vowels; sequences with ⟨в⟩, ⟨у⟩, ⟨ә⟩ for labialized consonants; and sequences with ⟨ӏ⟩ or ⟨ъ⟩ for ejective consonants or pharyngealized consonants and vowels. Tatar also has discontinuous digraphs. See Cyrillic digraphs for examples.
