Verb classes
Wistrish has two major verb class groups: root classes and derived classes.
Root classes
Root classes are independent verb classes: they are (by themselves) are not inherently derived from other verbs through suffixation (though in some cases it can happen as a part of a compound suffix).
- Strong verbs β the largest and the most frequently encountered independent verb class. Strong verbs undergo ablauting through tenses and aspects or in some cases reduplication.
- Preterite-present verbs β undergoes ablauting like the strong verbs, but non-past preterite-presents behave like the preterite of a strong verb, while past preterite-presents decline identically to the preterite of hollow verbs.
- Hollow verbs β a mainly minor class. There are only few actually independent hollow verbs: the vast majority of them come from hollow suffixes.
Derived classes
Derived classes are always derived from another verb (usually with aspectual suffixes), and each derived verb can be ultimately traced back to a root class verb. These are:
- Weak verbs (-πΎπ°π½) β verbs with causative / transitive meaning. Very similar to hollow verbs in formation, especially to the hollow II subclass, but with an infix -πΉ- in preterite.
- A/O verbs (-π½π°π½) β verbs with fientive meaning. Decline like present strong verbs in the present tense and like past gnomic-iterational verbs in preterite.
- A/E verbs (-ππ°π½) β verbs with cessative meaning. Similarly to fientive, declines like present strong verbs in non-past and like past passive verbs in preterite.
