Discovery and significance

The existence of the Tocharian languages and alphabet was not even suspected until archaeological exploration of the Tarim Basin by
Aurel Stein in the early 20th century brought to light fragments of manuscripts in an unknown language, dating from the 6th to 8th centuries AD.
It soon became clear that these fragments were actually written in two distinct but related languages belonging to a hitherto unknown branch of Indo-European, now known as Tocharian:
*Tocharian A (Turfanian, Agnean, or East Tocharian; natively ) of
Qarašähär (ancient ''Agni'', Chinese ''Yanqi'' and Sanskrit ''Agni'') and

documents from 3rd-century
Krorän and
Niya on the southeast edge of the Tarim Basin contain loanwords and names that appeared to scholars to come from a closely related language, referred to as Tocharian C.
However, this was found to be entirely flawed for the
Krorän part (see below, section "Tocharian C"). Recently, a dissertation authored by Niels Schoubben (

) has demonstrated that all the so-called Tocharian loanwords in Niya Prakrit were, in fact, Bactrian and pre-Bactrian loanwords, or resulted from fundamental misunderstandings of specific words and orthographies. His work definitively put an end to the "Tocharian C" hypothesis.
The discovery of Tocharian upset some theories about the relations of Indo-European languages and revitalized their study. In the 19th century, it was thought that the division between
centum and satem languages was a simple west–east division, with centum languages in the west. The theory was undermined in the early 20th century by the discovery of
Hittite, a centum language in a relatively eastern location, and Tocharian, which was a centum language despite being the easternmost branch. The result was a new hypothesis, following the

of
Johannes Schmidt, suggesting that the satem isogloss represents a linguistic innovation in the central part of the Proto-Indo-European home range, and the centum languages along the eastern and the western peripheries did not undergo that change.
Most scholars identify the ancestors of the Tocharians with the
Afanasievo culture of
South Siberia ( 3300–2500 BC), an early eastern offshoot of the steppe cultures of the Don-Volga area that later became the
Yamnayans.
Under this scenario, Tocharian speakers would have immigrated to the

. It is now clear that these people actually spoke
Bactrian, an
Eastern Iranian language, rather than the language of the Tarim manuscripts, so the term "Tocharian" is considered a misnomer. Nevertheless, it remains the standard term for the language of the Tarim Basin manuscripts.
In 1938,
Walter Bruno Henning found the term "four ''twγry''" used in early 9th-century manuscripts in Sogdian, Middle Iranian, and Uighur. He argued that it referred to the region on the northeast edge of the Tarim, including Agni and
Karakhoja, but not Kucha. He thus inferred that the colophon referred to the Agnean language.
Although the term ''twγry'' or ''toxrï'' appears to be the Old Turkic name for the Tocharians, it is not found in Tocharian texts.
The apparent self-designation ''ārśi'' appears in Tocharian A texts. Tocharian B texts use the adjective ''kuśiññe'', derived from ''kuśi'' or ''kuči'', a name also known from Chinese and Turkic documents.
The historian
Bernard Sergent compounded these names to coin an alternative term ''Arśi-Kuči'' for the family, recently revised to ''Agni-Kuči'', but this name has not achieved widespread usage.

. A common Proto-Tocharian language must precede the attested languages by several centuries, probably dating to the late 1st millennium BC.
Tocharian A is found only in the eastern part of the Tocharian-speaking area, and all extant texts are of a religious nature. Tocharian B, however, is found throughout the range and in both religious and secular texts. As a result, it has been suggested that Tocharian A was a
liturgical language, no longer spoken natively, while Tocharian B was the spoken language of the entire area.
The hypothesized relationship of Tocharian A and B as liturgical and spoken forms, respectively, is sometimes compared with the relationship between Latin and the modern

. However, in both of these latter cases, the liturgical language is the linguistic ancestor of the spoken language, whereas no such relationship holds between Tocharian A and B. In fact, from a phonological perspective Tocharian B is significantly more conservative than Tocharian A, and serves as the primary source for reconstructing Proto-Tocharian. Only Tocharian B preserves the following Proto-Tocharian features: stress distinctions, final vowels, diphthongs, and ''o'' vs. ''e'' distinction. In turn, the loss of final vowels in Tocharian A has led to the loss of certain Proto-Tocharian categories still found in Tocharian B, e.g. the vocative case and some of the noun, verb, and adjective declensional classes.
In their declensional and conjugational endings, the two languages innovated in divergent ways, with neither clearly simpler than the other. For example, both languages show significant innovations in the present active indicative endings but in radically different ways, so that only the second-person singular ending is directly cognate between the two languages, and in most cases neither variant is directly cognate with the corresponding

(PIE) form. The agglutinative secondary case endings in the two languages likewise stem from different sources, showing parallel development of the secondary case system after the Proto-Tocharian period. Likewise, some of the verb classes show independent origins, e.g. the class II preterite, which uses reduplication in Tocharian A (possibly from the reduplicated

) but long PIE ''ē'' in Tocharian B (possibly related to the long-vowel perfect found in Latin ''lēgī'', ''fēcī'', etc.).
Tocharian B shows an internal chronological development; three linguistic stages have been detected. The oldest stage is attested only in Kucha. There are also the middle ("classical") and the late stage.
Tocharian C
A third Tocharian language was first suggested by
Thomas Burrow in the 1930s, while discussing 3rd-century documents from
Krorän (Loulan) and
Niya. The texts were written in
Gandhari Prakrit, but contained loanwords of evidently Tocharian origin, such as ''kilme'' ('district'), ''ṣoṣthaṃga'' ('tax collector'), and ''ṣilpoga'' ('document'). This hypothetical language later became generally known as Tocharian C. It has also sometimes been called Kroränian or Krorainic.
In papers published posthumously in 2018, Klaus T. Schmidt, a scholar of Tocharian, presented a decipherment of 10 texts written in the
Kharoṣṭhī script. Schmidt claimed that these texts were written in a third Tocharian language he called .
He also suggested that the language was closer to Tocharian B than to Tocharian A.
In 2019 a group of linguists led by
Georges-Jean Pinault and
Michaël Peyrot convened in
Leiden

to examine Schmidt's translations against the original texts. They concluded that Schmidt's decipherment was fundamentally flawed, that there was no reason to associate the texts with Krörän, and that the language they recorded was neither Tocharian nor Indic, but Iranian.
In 2024, Schoubben conducted a systematic review of Niya Prakrit and the loanwords claimed as evidence for Tocharian C. He argued that most of the words in question could be explained as loanwords from
Bactrian or other
Iranian languages

, and found no compelling evidence for a Tocharian substrate. For example, Burrow proposed that ''aṃklatsa'', 'a type of camel', corresponded to Tocharian A ''āknats'' and Tocharian B ''aknātsa'' 'stupid, foolish', believing that this would refer to an 'untrained camel', from a Tocharian form *''anknats'' (with the negative prefix *''en-''). Not only does this etymology presuppose an ''ad hoc'' sound change from *-''nkn''- to *-''nkl''-, but the variant ''agiltsa'' also found in Niya becomes aberrant. Schoubben suggests that this is might be a Bactrian word, as camels originally come from Bactria, but could not find a convincing etymology. He had earlier argued that <ḱ> was used in Niya Prakrit to transcribe Bactrian -''šk''- (spelled ϸκ in the
Bactrian alphabet). For example, Burrow had tentatively connected ''maḱa'', a Niya Prakrit word for an unidentified food produced on farms, with Tocharian A ''malke'' 'milk', but Schoubben derives it from
Proto-Iranian *''māšaka-'' 'bean'.

Vowels
Tocharian A and Tocharian B have the same set of vowels, but they often do not correspond to each other. For example, the sound ''a'' did not occur in Proto-Tocharian. Tocharian B ''a'' is derived from former stressed ''ä'' or unstressed ''ā'' (reflected unchanged in Tocharian A), while Tocharian A ''a'' stems from Proto-Tocharian or (reflected as and in Tocharian B), and Tocharian A ''e'' and ''o'' stem largely from monophthongization of former diphthongs (still present in Tocharian B).
Diphthongs
Diphthongs occur in Tocharian B only.
Consonants

The following table lists the reconstructed phonemes in Tocharian along with their standard transcription. Because Tocharian is written in an alphabet used originally for Sanskrit and its descendants, the transcription reflects Sanskrit phonology, and may not represent Tocharian phonology accurately. The Tocharian alphabet also has letters representing all of the remaining Sanskrit sounds, but these appear only in Sanskrit loanwords and are not thought to have had distinct pronunciations in Tocharian. There is some uncertainty as to actual pronunciation of some of the letters, particularly those representing palatalized obstruents (see below).

# The sound ''ṅ'' occurs only before ''k'', or in some clusters where a ''k'' has been deleted between consonants. It is clearly phonemic because sequences ''nk'' and ''ñk'' also exist (from
syncope of a former ''ä'' between them).
Morphology
Nouns
Tocharian has completely re-worked the
nominal declension system of Proto-Indo-European. The only cases inherited from the proto-language are nominative, genitive,
accusative
In grammar, the accusative case (abbreviated ) of a noun is the grammatical case used to receive the direct object of a transitive verb.
In the English language, the only words that occur in the accusative case are pronouns: "me", "him", "her", " ...
, and (in Tocharian B only) vocative; in Tocharian the old accusative is known as the ''oblique'' case. In addition to these primary cases, however, each Tocharian language has six cases formed by the addition of an invariant suffix to the oblique case — although the set of six cases is not the same in each language, and the suffixes are largely non-cognate. For example, the Tocharian word ' (Toch B), ' (Toch A) "horse" < PIE ''*eḱwos'' is declined as follows:
The Tocharian A instrumental case rarely occurs with humans.
When referring to humans, the oblique singular of most adjectives and of some nouns is marked in both varieties by an ending ''-(a)ṃ'', which also appears in the secondary cases. An example is ' (Toch B), ' (Toch A) "man", which belongs to the same declension as above, but has oblique singular ' (Toch B), ' (Toch A), and corresponding oblique stems ' (Toch B), ' (Toch A) for the secondary cases. This is thought to stem from the generalization of ''n''-stem adjectives as an indication of determinative semantics, seen most prominently in the weak adjective declension in the
Germanic languages
The Germanic languages are a branch of the Indo-European languages, Indo-European language family spoken natively by a population of about 515 million people mainly in Europe, North America, Oceania, and Southern Africa. The most widely spoke ...
(where it cooccurs with definite articles and determiners), but also in Latin and Greek ''n''-stem nouns (especially proper names) formed from adjectives, e.g. Latin ''Catō'' (genitive ''Catōnis'') literally "the sly one" < ''catus'' "sly", Greek ''Plátōn'' literally "the broad-shouldered one" < ''platús'' "broad".
Verbs
In contrast, the
verbal conjugation system is quite conservative. The majority of Proto-Indo-European verbal classes and categories are represented in some manner in Tocharian, although not necessarily with the same function. Some examples: athematic and thematic present tenses, including null-, ''-y-'', ''-sḱ-'', ''-s-'', ''-n-'' and ''-nH-'' suffixes as well as ''n''-infixes and various laryngeal-ending stems; ''o''-grade and possibly lengthened-grade perfects (although lacking reduplication or augment); sigmatic, reduplicated, thematic, and possibly lengthened-grade aorists; optatives; imperatives; and possibly PIE subjunctives.
In addition, most PIE sets of endings are found in some form in Tocharian (although with significant innovations), including thematic and athematic endings, primary (non-past) and secondary (past) endings, active and mediopassive endings, and perfect endings. Dual endings are still found, although they are rarely attested and generally restricted to the third person. The mediopassive still reflects the distinction between primary ''-r'' and secondary ''-i'', effaced in most Indo-European languages. Both root and suffix ablaut is still well-represented, although again with significant innovations.
Categories
Tocharian verbs are conjugated in the following categories:
*Mood: indicative, subjunctive, optative, imperative.
*Tense/aspect (in the indicative only): present, preterite, imperfect.
*Voice: active, mediopassive, deponent.
*Person: 1st, 2nd, 3rd.
*Number: singular, dual, plural.
*Causation: basic, causative.
*Non-finite: active participle, mediopassive participle, present gerundive, subjunctive gerundive.

=Present indicative
=
The most complex system is the present indicative, consisting of 12 classes, 8 thematic and 4 athematic, with distinct sets of thematic and athematic endings. The following classes occur in Tocharian B (some are missing in Tocharian A):
*I: Athematic without suffix < PIE root athematic.
*II: Thematic without suffix < PIE root thematic.
*III: Thematic with PToch suffix ''*-ë-''.
Mediopassive only. Apparently reflecting consistent PIE ''o'' theme rather than the normal alternating ''o/e'' theme.
*IV: Thematic with PToch suffix ''*-ɔ-''. Mediopassive only. Same PIE origin as previous class, but diverging within Proto-Tocharian.
*V: Athematic with PToch suffix ''*-ā-'', likely from either PIE verbs ending in a syllabic laryngeal or PIE derived verbs in ''*-eh₂-'' (but extended to other verbs).
*VI: Athematic with PToch suffix ''*-nā-'', from PIE verbs in ''*-nH-''.
*VII: Athematic with infixed nasal, from PIE infixed nasal verbs.
*VIII: Thematic with suffix ''-s-'', possibly from PIE ''-sḱ-''?
*IX: Thematic with suffix ''-sk-'' < PIE ''-sḱ-''.
*X: Thematic with PToch suffix ''*-näsk/nāsk-'' (evidently a combination of classes VI and IX).
*XI: Thematic in PToch suffix ''*-säsk-'' (evidently a combination of classes VIII and IX).
*XII: Thematic with PToch suffix ''*-(ä)ññ-'' < either PIE ''*-n-y-'' (denominative to n-stem nouns) or PIE ''*-nH-y-'' (deverbative from PIE ''*-nH-'' verbs).

likewise has 12 classes, denoted ''i'' through ''xii''. Most are conjugated identically to the corresponding indicative classes; indicative and subjunctive are distinguished by the fact that a verb in a given indicative class will usually belong to a different subjunctive class.
In addition, four subjunctive classes differ from the corresponding indicative classes, two "special subjunctive" classes with differing suffixes and two "varying subjunctive" classes with root ablaut reflecting the PIE perfect.
Special subjunctives:
*iv: Thematic with suffix ''i'' < PIE ''-y-'', with consistent palatalization of final root consonant. Tocharian B only, rare.
*vii: Thematic (''not'' athematic, as in indicative class VII) with suffix ''ñ'' < PIE ''-n-'' (palatalized by thematic ''e'', with palatalized variant generalized).
Varying subjunctives:
*i: Athematic without suffix, with root ablaut reflecting PIE ''o''-grade in active singular, zero-grade elsewhere. Derived from PIE perfect.
*v: Identical to class i but with PToch suffix ''*-ā-'', originally reflecting laryngeal-final roots but generalized.

has 6 classes:
*I: The most common class, with a suffix ''ā'' < PIE ''Ḥ'' (i.e. roots ending in a laryngeal, although widely extended to other roots). This class shows root ablaut, with original ''e''-grade (and palatalization of the initial root consonant) in the active singular, contrasting with zero-grade (and no palatalization) elsewhere.
*II: This class has reduplication in Tocharian A (possibly reflecting the PIE reduplicated aorist). However, Tocharian B has a vowel reflecting long PIE ''ē'', along with palatalization of the initial root consonant. There is no
ablaut
In linguistics, the Indo-European ablaut ( , from German ) is a system of apophony (regular vowel variations) in the Proto-Indo-European language (PIE).
An example of ablaut in English is the strong verb ''sing, sang, sung'' and its relate ...
in this class.
*III: This class has a suffix ''s'' in the 3rd singular active and throughout the mediopassive, evidently reflecting the PIE sigmatic
aorist
Aorist ( ; abbreviated ) verb forms usually express perfective aspect and refer to past events, similar to a preterite. Ancient Greek grammar had the aorist form, and the grammars of other Indo-European languages and languages influenced by the ...
. Root ablaut occurs between active and mediopassive. A few verbs have palatalization in the active along with ''s'' in the 3rd singular, but no palatalization and no ''s'' in the mediopassive, along with no root ablaut (the vowel reflects PToch ''ë''). This suggests that, for these verbs in particular, the active originates in the PIE sigmatic aorist (with ''s'' suffix and ''ē'' vocalism) while the mediopassive stems from the PIE perfect (with ''o'' vocalism).
*IV: This class has suffix ''ṣṣā'', with no ablaut. Most verbs in this class are causatives.
*V: This class has suffix ''ñ(ñ)ā'', with no ablaut. Only a few verbs belong to this class.
*VI: This class, which has only two verbs, is derived from the PIE thematic aorist. As in Greek, this class has different endings from all the others, which partly reflect the PIE secondary endings (as expected for the thematic aorist).
All except preterite class VI have a common set of endings that stem from the PIE perfect endings, although with significant innovations.
=Imperative
=
The
imperative likewise shows 6 classes, with a unique set of endings, found only in the second person, and a prefix beginning with ''p-''. This prefix usually reflects Proto-Tocharian ''*pä-'' but unexpected connecting vowels occasionally occur, and the prefix combines with vowel-initial and glide-initial roots in unexpected ways. The prefix is often compared with the Slavic perfective prefix ''po-'', although the phonology is difficult to explain.
Classes i through v tend to co-occur with preterite classes I through V, although there are many exceptions. Class vi is not so much a coherent class as an "irregular" class with all verbs not fitting in other categories. The imperative classes tend to share the same suffix as the corresponding preterite (if any), but to have root vocalism that matches the vocalism of a verb's subjunctive. This includes the root ablaut of subjunctive classes i and v, which tend to co-occur with imperative class i.

have related formations. The optative is generally built by adding ''i'' onto the subjunctive stem. Tocharian B likewise forms the imperfect by adding ''i'' onto the present indicative stem, while Tocharian A has 4 separate imperfect formations: usually ''ā'' is added to the subjunctive stem, but occasionally to the indicative stem, and sometimes either ''ā'' or ''s'' is added directly onto the root. The endings differ between the two languages: Tocharian A uses present endings for the optative and preterite endings for the imperfect, while Tocharian B uses the same endings for both, which are a combination of preterite and unique endings (the latter used in the singular active).
Endings
As suggested by the above discussion, there are a large number of sets of endings. The present-tense endings come in both thematic and athematic variants, although they are related, with the thematic endings generally reflecting a theme vowel (PIE ''e'' or ''o'') plus the athematic endings. There are different sets for the preterite classes I through V; preterite class VI; the imperative; and in Tocharian B, in the singular active of the optative and imperfect. Furthermore, each set of endings comes with both active and mediopassive forms. The mediopassive forms are quite conservative, directly reflecting the PIE variation between ''-r'' in the present and ''-i'' in the past. (Most other languages with the mediopassive have generalized one of the two.)
The present-tense endings are almost completely divergent between Tocharian A and B. The following shows the thematic endings, with their origin:
Comparison to other Indo-European languages
In traditional Indo-European studies, no hypothesis of a closer genealogical relationship of the Tocharian languages has been widely accepted by linguists. However,
lexicostatistical and
glottochronological approaches suggest the

, including
Hittite, might be the closest relatives of Tocharian.
As an example, the same Proto-Indo-European root (but not a common suffixed formation) can be reconstructed to underlie the words for 'wheel': Tocharian A ''wärkänt'', Tokharian B ''yerkwanto'', and Hittite ''ḫūrkis''.
Contact with other languages
Michaël Peyrot argues that several of the most striking typological peculiarities of Tocharian are rooted in a prolonged contact of Proto-Tocharian with an early stage of
Proto-Samoyedic in South Siberia. This might explain the merger of
all three stop series (e.g. *t, *d, *dʰ > *t), which must have led to a huge number of
homonyms, restructuring of the vowel system, development of
