Old Tibetan refers to the earliest attested form of Tibetan language, reflected in documents from the adoption of writing by the Tibetan Empire in the mid-7th century to the early 9th century.In 816 CE, during the reign of Tibetan King Sadnalegs, literary Tibetan underwent comprehensive standardization, resulting in Classical Tibetan.
Old Tibetan is characterised by many features that are lost in Classical Tibetan, including my- rather than m- before the vowels -i- and -e-, the cluster sts- which simplifies to s- in Classical Tibetan, and a reverse form of the "i" vowel letter (gi-gu). Aspiration was not phonemic and many words were written indiscriminately with consonants from the aspirated or unaspirated series. Most consonants could be palatalized, and the palatal series from the Tibetan script represents palatalized coronals. The sound conventionally transcribed with the letter འ (Wylie: 'a) was a voiced velar fricative, while the voiceless rhotic and lateral are written with digraphs ཧྲ (hr) and ལྷ (lh). The following table is based on Hill's analysis of Old Tibetan:
| Nasal | pronounced as /link/ | pronounced as /link/ | pronounced as /link/ (ṅ) | ||
|---|---|---|---|---|---|
| Plosive | pronounced as /link/ | pronounced as /link/ | pronounced as /link/ | ||

In Old Tibetan, the glide pronounced as /link/ occurred as a medial, but not as an initial.The Written Tibetan letter ཝ w was originally a digraph representing two Old Tibetan consonants pronounced as /ɦw/.
In Old Tibetan, syllables can be quite complex with up to three consonants in the onset, two glides, and two coda consonants. This structure can be represented as, with all positions except C3 and V optional. This allows for complicated syllables like བསྒྲིགས "arranged" and འདྲྭ
A voicing contrast only exists in slot C3 and spreads to C1 and C2 so སྒོ sgo "door" would be realized as pronounced as /[zɡo]/ while སྐུ "body" would be pronounced as /[sku]/. Final consonants are always voiceless e.g. འཛིནད་
Palatalization pronounced as //Cʲ// was phonemically distinct from the onset cluster pronounced as //Cj//. This produces a contrast between གཡ (g.y) pronounced as //ɡj// and གྱ (gy) pronounced as //ɡʲ//, demonstrated by the minimal pair གཡང་ g.yaṅ "sheep" and གྱང་ gyaṅ "also, and". The sounds written with the palatal letters ཅ c, ཇ j, ཉ ny, ཞ zh, and ཤ sh were palatalized counterparts of the phonemic sounds ཙ ts, ཛ dz, ན n, ཟ z, and ས s.
Case markers are affixed to entire noun phrases, not to individual words (i.e. Gruppenflexion). Old Tibetan distinguishes the same ten cases as Classical Tibetan:
However, whereas the locative, allative, and terminative gradually fell together in Classical Tibetan (and are referred to the indigenous grammatical tradition as the la don bdun), in Old Tibetan these three cases are clearly distinguished. Traditional Tibetan grammarians do not distinguish case markers in this manner, but rather distribute these case morphemes (excluding -dang and -bas) into the eight cases of Sanskrit.
Old Tibetan transitive verbs were inflected for up to four stems, while intransitive verbs only had one or two stems. In the active voice, there was an imperfective stem and a perfective stem, corresponding to the Classical Tibetan present and past stems respectively. Transitive verbs also may have two passive voice stems, a dynamic stem and stative stem. These two stems in turn correspond to the Classical future and imperative stems.[1]
Old Tibetan has three first person singular pronouns ང་ ṅa, བདག་, and ཁོ་བོ་, and three first-person plural pronouns ངེད་, བདག་ཅག་, and འོ་སྐོལ་ . The second person pronouns include two singulars ཁྱོད་ and ཁྱོ(ན)་འདའ་ -'da' and a plural ཁྱེད་ .
