3.4.6.	Mood
Mood expresses the attitude/judgment of the speaker towards/on what he is saying as a logical proposition. Mao Naga has thirty of them:
1.  The Incumbency modal     2.  The Non-deontic obligative     3.  The Dubitative     4.  The mood of Stressed possibility     5.  The Thwarted desiderative     6.  The Permissive     7.  The Optative     8.  The Suggestive (hortative)     9.  The Definite     10.  The mood of Individual choice     11.  The Decisive-intentive     12.  The mood of Ability     13.  The mood of Mental readiness to brave circumstances     14.  The mood of Action contrary to earlier state of affairs     15.  The Subjuctive     16.  The Conditional     17.  The Contingency mood     18.  The Concessive or pseudo-conditional     19.  The mood of Unconcerned neglect     20.  The mood of Hearsay     21.  The Inferential     22. The mood of Seriousness     23. The mood of Perceived Undesirability of/and (hence) apprehensive concern about the   action     24.  The mood of Unexpected, surprising action     25.  The Completive     26.  The mood of Determination     27.  The mood of Temporal concomitance     28.  The mood of Motivated action     29.  The Imperative     30.  The Incompletive
This list excludes the unmarked indicative mood.
All the markers of mood are suffixes except the Non-deontic Obligative whose expression is syntactic rather than morphological, and for that reason, strictly speaking, does not belong here. It is included here because the formal expression is fossilized, crusted. Two moods viz. the moods of Stressed Possibility and Unconcerned Neglect are expressed in terms of or built upon the Concessive mood. Unlike tense, but like aspect, two moods can co-occur. The following illustrates the co-occurence of (the) two moods (of ability and dubitation).

3.4.6.1.	The Incumbency or Deontic Mood
The Incumbency or Deontic mood expresses an obligation-moral or otherwise-, an imperative of some sort. It is marked by the postposing of (o)pha, whose meaning is not entirely clear-elsewhere it means ‘time’ - to the participial/gerundial form of the verb. It signals correct, generally expected, required behaviour.
