Tsakxa verbs
Verbs in Tsakxa are comparatively heavily inflected, conjugating by aspect, mood and voice. There are two classes of verbs, the monopartite verbs (which have a single stem and are conjugated regularly) and the bipartite verbs (which have a bipartite stem and whose conjugation is far more complex and irregular).
Monopartite verbs
Monopartite verbs are by far the more common type of verb in Tsakxa. They have a single stem, as implied by the name, and take only suffixes for inflection.
Aspect
All verbs carry inflection for aspect. In monopartite verbs, this is accomplished by the addition of a suffix.
Perfective aspect
The Perfective aspect implies a single action, complete and independent of any other action and is formed by (e)ngxu (the /e/ assimilates to a preceding vowel and causes lenition of /t/ to /s/ and /p/ to /f/ in preceding consonants). For example:
- Sesu-sa ta-ngxu - I saw/see my sister at one point (sister.TOPIC-PERSONAL see-PERF)
