The Proto-Kra language is the reconstructed ancestor of the Kra languages. It was reconstructed in 2000 by Weera Ostapirat in his Ph.D. dissertation.

Lower-level reconstructions[edit]

Ostapirat (2000) provided preliminary phonological reconstructions for several lower-level groupings before attempting a reconstruction of Proto-Kra.

  • Proto-Kra
    • Proto-South-Western Kra
      • Proto-Western Kra (Gelao, Lachi)
      • Proto-Southern Kra (Laha)
    • Proto-Central-East Kra
      • Proto-Central Kra (Paha)
      • Proto-Eastern Kra (Buyang, Qabiao)

Tones[edit]

Proto-Kra had an A–B–C–D tonal system typical of other Tai–Kadai languages (see Proto-Tai language#Tones). The tonal descriptions below are from Ostapirat (2000:237).

  1. *A: *A is one of the most common tones.
  2. *B: *B and *D are phonetically similar, as reflexes of tone *D are often the same as those of *B. This regularly occurs in all Kra languages except for Qabiao.
  3. *C: *C is usually accompanied by glottal constriction and may have originally had a creaky or tense laryngeal quality. Some Gelao varieties and Yalang Buyang display the same reflex for
  4. *D: *D is the only tone to occur exclusively in closed syllables.

The following table of phonetic characteristics of Proto-Kra tones was adapted from Ostapirat (2000:237).

Proto-Kra Tonal Characteristics
*A *B *C *D
Type of final sonorants, vowels lax larynx (?) tense larynx stops
Voicing voiced unvoiced unvoiced unvoiced
Vocal cords vibrating wide open closed closed
Vowel duration long medium short medium
