“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.”

qroqqa Indicating an unreal situation. English has one verb-form for marking irrealis mood: the first-person and third-person singular 'were', part of the verb 'be'. This is used with verb-subject inversion in conditional clauses ('Were I younger, I would go') and optionally in non-inverted hypothetical conditionals ('If I were/was younger, I would go') and some others (sometimes after 'as if'). Traditionally called the past subjunctive, and indeed historically derived from that. Jul 31, 2008
