How did you come up with the idea of having pronoun forms indicate realis / irrealis?
A. In Kisi this type of lengthening and raising the tone of the subject pronouns is used to mark the past habitual form. I liked this idea a lot so I borrowed it and expanded its role in Tseeyo. There are no overt realis / irrealis markers in these related natlangs. A distantly related language, Wolof, uses different forms of pronouns to indicate inflections on all its verbs. The verbs themselves do not change.
