Consonants

Proto-Tibetan–Burman has at least 23 consonants (Matisoff 2003:15). Some descendants of Proto-Tibetan–Burman, especially the Qiangic languages

Vowels

Proto-Tibeto-Burman vowels can be split into primary and secondary sets. Modern-day Tibeto-Burman languages have anywhere from five vowels (Written Tibetan and Jingpho) to dozens of monophthongs and diphthongs (Loloish

Preservation of stops

Sino-Tibetan languages go through a series of four stages in which final stops and nasals gradually decay (Matisoff 2003:238-239).
  1. The six final stops and nasals, *-p, *-t, *-k, *-m, *-n, *-ŋ, are all intact. Written Tibetan, Lepcha, Kanauri, Garo, and Cantonese are currently in this stage.
  2. One or more final consonants have been reduced or dropped. In Jingpho and Nung, the velars (*-k) are replaced by glottal stops (), while in other languages they are completely dropped. In Mandarin Chinese, all final stops are dropped, and *-m has merged with *-n.
  3. All finals stops become glottal stops or constrictions (such as creaky voices), and final nasals may be replaced by nasality in the preceding consonant. Languages currently in this stage include modern Burmese and Lahu

    .
  4. There are no glottal or nasal traces of former final consonants left in the syllables.

Syntax

Proto-Tibeto-Burman was a verb-final (subject–object–verb or SOV) language.

Syllable structure

According to James Matisoff
James Matisoff
James A. Matisoff is a professor emeritus of Linguistics at the University of California, Berkeley and noted authority on Tibeto-Burman languages and other languages of mainland Southeast Asia....

, Proto-Tibeto-Burman syllables typically consist of the following structure (Matisoff 2003:11-13).
  • P1: first prefix - optional
  • P2: second prefix - optional
  • Ci: initial consonant
  • G: glide - optional
  • V: vowel (optionally lengthened)
  • Cf: final consonant
  • s: suffix - optional


The following types of changes in syllable structure have been attested in Tibeto-Burman languages (Matisoff 2003:155). (Note: "Sesquisyllable" is a word coined by James Matisoff

Prefixes

Matisoff postulates the following derivational prefixes.
  • *s- — This root is used for the directive, causative, or intensive. It also appears in words for animals and body parts.
  • *ʔa- / *(ʔ)ə / *ʔə̃ / *ʔaŋ / *ʔak — This glottal prefix is used for kinship functions and the third person possessive.
  • *m- — Before verb roots, this prefix signifies inner-directed states or actions, such as stativity, intrasitivity, durativity, and reflexivity. Before noun roots, it is used as a third person possessive prefix.
  • *r- — Before verbs, this prefix is used as a "directive." It is also used before a wide variety of semantically unrelated noun roots.
  • *b- — This prefix is often used before transitive verbs, and usually marks the past (with suffix *-s, creating a *b- -s circumfix
    Circumfix

    ) and future (with a null suffix).
  • *g- — This velar prefix has a third person pronominal function before noun roots. It is also used before a wide variety of semantically unrelated noun roots. Before verb roots, it is used for the present and future tenses. In Proto-Lolo–Burmese, the unvoiced velar prefix *k- is used commonly used before animal names.


Other constructed prefixes include *l- and *d-.

Circumfixes

Circumfixes have also been reconstructed for Proto-Tibeto-Burman.

In Written Tibetan, s- -n and s- -d are collective circumfixes used in kinship terms (Matisoff 2003:453).

Suffixes

Three Proto-Tibeto-Burman dental suffixes, *-n, *-t, and *-s, are highly widespread, but their semantics are difficult to reconstruct (Matisoff 2003:439). The suffixes *-s, *-h, and *-ʔ are often developed into tones in many Tibeto-Burman languages, and are thus highly "tonogenetically potent" (Matisoff 2003:474).
  • *-n – This suffix has a variety of functions, including nominalizing, transitivizing, and collectivizing (or pluralizing). The nominalizing function is attested in Lepcha
    Lepcha language
    Lepcha language, or Róng language , is a Himalayish language spoken by the Lepcha people in Sikkim and parts of West Bengal, Nepal and Bhutan.-Population:...

     as -m or -n and in Written Tibetan as -n. The transitivizing form is rare, and has only been attested in Kanauri. Finally, the collectivizing/pluralizing function is found not only in many modern-day Tibeto-Burman languages, but also in Old Chinese as well.
  • *-t – This suffix is used as a nominalizer. It occurs in Jingpho
    Jingpho language

     as -t and Written Tibetan as -d. Other functions include verbalizing noun roots and making intransitive or stative verbs into transitive or causative ones (Matisoff 2003:457). In other cases, *-t appears to have no obvious function. The *-t suffix also occurs in Old Chinese, but its semantic function is unclear.
  • *-s – Not easily distinguishable from *-t, this proto-suffix is preserved in written Tibetan, West Himalayish languages

     and Kukish languages).
  • *-k – This velar suffix occurs in the Kukish languages and also in Old Chinese. Its semantic function is still unknown. However, Pulleybank assigns a distributive sense to the *-k suffix, but only in relation to pronominal forms (LaPolla 2003:26).
  • *ʔay – This proto-morpheme means "to go", and can be attached to various roots as a palatal suffix to signify motion away from the deictic center. This fully syllabic proto-morpheme has now been grammaticalized and reduced to palatal offglides in modern-day Tibeto-Burman languages.
  • *ya / *za / *tsa / *dza – Meaning "child" or "little one", this proto-morpheme appears in Tibeto-Burman languages as a palatal suffix (-j), and has also been reconstructed in several ways. Its purpose is mainly diminutive

    . Matisoff (2003) also notes that high front vowels tend to be used for diminutive functions.
  • *-way / *-ray – This proto-copula can also appear as a palatal suffix (-j) and occurs in roots carrying abstract grammatical meanings, such as articles, pronouns, and deictics (Matisoff 2003:487).
