Datapoint Principense/Tense-aspect systems
Günther (1973) proposes an analysis of the tense-aspect-mood system which has been criticized in Maurer (1997). The main point is that Günther failed to see that the form a (his aspect III, continuative) is not a tense-aspect marker on its own, but a contracted form of both sa and ka.
