Yakut and the
Buryat languages are particularly strong. The influence of Russian in general is overwhelming (in 1979, 75.2% of the Evenkis spoke Russian, rising to 92.7% in 2002). Evenki children were forced to learn Russian at Soviet residential schools, and returned with a “poor ability to speak their mother tongue...". The Evenki language varies considerably among its dialects, which are divided into three large groups: the northern, the southern and the eastern dialects.

P. S. Pallas in the late 18th century, and then in a more formal linguistic study by
M. A. Castren in the mid-19th century, regarded as a "pioneer treatise" in the field of Tungusology. The exact internal structure of the Tungusic family is a matter of some debate. Some scholars propose two sub-families: one for Manchu, and another for all the other Tungusic languages, including Evenki.

Ethnologue divides Tungusic into two sub-families, Northern and Southern, with Evenki alongside
Even and
Negidal in the Northern sub-family, and the Southern family itself subdivided into Southwestern (among which Manchu) and Southeastern (

Others propose three or more sub-families, or at the extreme a
continuum with Manchu at one end and Evenki at the other.

Evenks in China also speak several dialects. According to
Ethnologue, the Hihue or Hoy dialect is considered the standard; Haila’er, Aoluguya (Olguya), Chenba’erhu (Old Bargu), and Morigele (Mergel) dialects also exist. Ethnologue reports these dialects differ significantly from those in Russia.
Some works focused on individual Russia dialects include (Barguzin), (Tommot), and (Sakhalin).
Phonology
The Evenki language typically has CV syllables but other structures are possible. Bulatova and Grenoble list Evenki as having 11 possible vowel phonemes; a classical five-vowel system with distinctions between long and short vowels (except in ) and the addition of a long and short ,
while Nedjalkov claims that there are 13 vowel phonemes. Evenki has a moderately small consonant inventory; there are 18 consonants (21 according to Nedjalkov 1997) in the Evenki language and it lacks glides or semivowels.

, Evenki employs back-front vowel harmony—suffix vowels are matched to the vowel in the root. However, some vowels – – and certain suffixes no longer adhere to the rules of vowel harmony.
Knowledge of the rules of vowel harmony is fading, as vowel harmony is a complex topic for elementary speakers to grasp, the language is severely endangered (Janhunen), and many speakers are multilingual.
Syllable structure
Possible syllable structures include V, VC, VCC, CV, CVC, and CVCC. In contrast to dialects in Russia, dialects in China do not have /k/, /ŋ/, or /r/ in word-initial position.
Alphabets
Russia
The creation of the Evenki alphabet began in the 1920s. In May 1928, researcher
G. M. Vasilevich () prepared for the Evenk students who studied in Leningrad the “Memo to Tungus-vacationers”. It was a small textbook duplicated on the glass. It used the Vasilyevich Evenki alphabet on a Latin graphic basis. A year later, she compiled the “First Book for Reading in the Tungus Language” (''Әwәnkil dukuwuntin''). This alphabet had the following composition: Aa Bb Çç HH Dd Ӡӡ Ee Әә Gg Hh Ii Kk Ll Mm Nn Ŋŋ Oo Pp Rr Ss Tt Uu Ww Yy; it also included diacritical marks: a macron to indicate the longitude of the sound and a sub-letter comma to indicate palatalization.
In 1930, it was decided to create a written language for the majority of the peoples of the North of the USSR. The Latin alphabet was chosen as its graphic basis. In the same year, the project of the Evenki alphabet was proposed by Ya. P. Alcor. This project differed from Vasilevich's alphabet only by the presence of letters for displaying Russian borrowings (C c, F f, J j, W w, Z z), as well as using V v instead of W w. After some refinement, the letter ''Çç'' was replaced by C c, V v by W w, and the letter Y y was excluded.
In May 1931, the Evenki romanized alphabet was officially approved, and in 1932 regular publishing began on it.
The basis of the literary language was laid the most studied Nepsky dialect (north of the Irkutsk region).
The official
Latinized Evenk alphabet, in which book publishing and schooling were conducted, looked like this:

. The script has one additional letter, ӈ, to indicate /ŋ/; it is used only inconsistently in printed works, due to typographical limitations. Boldyrev's dictionary uses ң instead. Other sounds found in Evenki but not Russian, such as /dʒ/, lack devoted letters. Instead д stands in for both /d/ and /dʒ/; when the latter pronunciation is intended, it is followed by one of Cyrillic's
iotified letters, similar to the way those letters cause

is easily recognizable and carries only one piece of meaning. Evenki pronouns distinguish between singular and plural as well as inclusive and exclusive in the first person. The Evenki language has a rich case system — 13 cases, though there is some variation among dialects — and it is a nominative–accusative language. Evenki differentiates between alienable and inalienable possession: alienable possession marks the possessor in the

harshly criticised the "child-like" literary language, and in a 1930s monograph predicted it would quickly go extinct. Although textbooks through the 8th grade have been published, "Literary Evenki has not yet achieved the status of a norm which cut across dialects and is understood by speakers of some dialects with great difficulty".
However, despite its failure to gain widespread acceptance, within its dialectal base of roughly 5,000 people, it survived and continues in use up to the present.
Since the 1930s, "folklore, novels, poetry, numerous translations from Russian and other languages", textbooks, and dictionaries have all been written in Evenki.
In
Tura (former administrative center of the
Evenk Autonomous Okrug), the local newspaper includes a weekly supplement written in Evenki.
Language shift and multilingualism
There is a large quantity of Russian loan words in Evenki, especially for technologies and concepts that were introduced by the Russian pioneers in Siberia. "Evenki is spoken in regions with heavy multilingualism. In their daily life the people come into contact with Russian, Buriat and Yakut, and each of these languages had affected the Evenki language. Russian is the lingua franca of the region, part of the Evenki population is bilingual, and part trilingual. All Evenki know Russian relatively well."
In 1998 there were approximately 30,000 ethnic Evenkis living in Russia and about 1/3 of them spoke the language. Even a decade ago Bulatova was trying to warn speakers and linguists alike: "There is widespread loss of Evenki and the language can be considered seriously endangered".
According to the
2002 Russian census

Russian as their "language of intercultural communication". Janhunen predicted that all of these languages, including Mongolian, were likely to lose ground to Chinese in coming years. However Chaoke noted more than a decade later that the usage rate of Evenki remained quite high, and that it was still common to find Evenki speakers who were proficient in three, four, or even five languages.

There is little information regarding revival efforts or Evenki's status now. In 1998, the language was taught in preschools and primary schools and offered as an option in 8th grade.
