3.4.6.2.	The Non-deontic Obligative
The Non-deontic Obligative mood expresses the amoral indispensability of the action and is more forceful than the deontic mood. It is expressed by the complex v-mo-li shü- where v stands for verb - which means ‘if (li) not (mo), it is bad (shü)’. Literally - only literally - then, this complex added to the finite verb of the sentence would mean that if the action suggested by the verb is not gone through, undesirable consequences may follow. Although the grammatically crusted formal expression has not quite yielded a noncompostional meaning, the literal meaning no longer penetrates native speaker consciousness.

A cogent piece of evidence v+mo+li+shü is not straight forwardly syntactic and has become frozen as a part of the subliminal self of the native speaker is that there is no v-li-shü, which should logically be the negative counterpart of v+mo-li shü. (The negative of this mood is v-shü See 3.4.13.5.12)

3.4.6.3.	The Dubitative
The Dubitative mood which expresses doubt of varying degrees about the proposition is signalled by amolo suffixed to the verb.
