The conditional verb in Ŋʒädär (marked by -OlOb- directly on the stem) can be used for a variety of uses, even strictly indicative/realis uses. It has three main usages:
1. Irrealis / Conditional
The presence of -OlOb- on a verb is most commonly used to signal a conditional construction. Usually, both the protasis and apodosis are marked with -OlOb-, especially if they are of the same tense. However, if if the protasis is in the past, and the apodosis in the present, you sometimes only get -OlOb- on the protasis. The protasis often comes before the apodosis, but this is not mandatory. In the case of the protasis coming after, however, the postposition -ok'an is mandatorily suffixed to the verb or to a third person dummy obviative pronoun. Here, a slight indication that the irrealis is somewhat 'infinitive-like' appears.
2. Statements about VPs
What in English would be expressed as 'it is unfortunate/good/... that ..." would, in Ŋʒädär be constructed as
unfortunate/good/... VP (with V having -OlOb-)
An interesting difference is that for proper adjectives, use of the absolutive indicates that the statement is realis, whereas use of the complement case indicates that the statement is irrealis. For nouns, it is dative vs. complement, where the dative indicates realis. For "improper adjectives" (or adverbally inclined adjectives, see this), the distinction is maintained by omitting the absolutive marker in the realis, and the use of the complement case in the irrealis.
3. Denoting wishes and desires
If used in a statement with no apparent apodosis, and no apparent adjective or NP (or even other VP) to parse as qualifying the quality of the statement, -OlOb- cannot be parsed as marking neither a condition nor a result, and will be parsed as expressing a desired circumstance.
