- adj. Of a verb: inflected to indicate that an act or state of being is not a fact.
Sorry, no etymologies found.
Another interesting aspect of this model is the prediction that while the so-called "secondary" endings ie. the objective non-progressive endings in this model: *-m, *-s, *-t came to dominate the function of irrealis in the Core IE dialects, the original grammar must have allowed for both objective and subjective non-progressive endings.
Likewise *-i is absent in all other irrealis moods ie. the optative, and likely too, the subjunctive.
Thus we can say that the first person subjunctive is a more certain statement of irrealis when compared to all other persons.
