Beyond the reduplication mentioned here, Ŋʒädär is rich in moods and aspects. Its tense system permits rather complicated things by auxiliaries, but for a clause without an auxiliary, there are two tenses: past and non-past, which are not distinguished in all moods. Auxiliaries are used for specific times such as 'yesterday', and in combination with aspect forms, obtain forms like 'until yesterday', 'since yesterday', 'intermittently a long time ago', etc.
Non-past is generally not marked by any morpheme, although a handful of verbs do get the marker -vul/vıl/vil/vül- in the inverse when the verb is non-past, instead of the usual marker. These are verbs of perception, of opinion, and of mental states in general. The morpheme originates with the noun *vurl that in Proto-ŊƷD signified the 'soul' of animals. The reason for this only appearing in the non-past tense may originate with some kind of belief that animal cognition did not much care about the past - that animals were more present-centered than man, and this fits with ideas about animal psychology in ŊƷD superstitions throughout the ŊƷD tribes.
The past is marked by a suffix after the aspect marker, but before the person marking. This suffix appears in the realis, optative and dubitative, and takes the form -(I)c'l(I)-.
Beyond this, we get the aspect system. The location of the aspect marker is immediately after the verb root, sometimes causing slight morphophonological alterations of the root itself. The perfective marker has somewhat merged with modal markers.
After stops, this mutates into
Before velar sounds and -w-, the -l- is lost, and before -v-, it's lost while turning the -v- into -w-. The -m-/-w- part can cause a variety of other things as well: -pw- and -tw- tend to become -kw-. -nm- becomes -m(:)- or -n(:)-. Depending on dialect, -wm- becomes -m(:)-.
Note: intrinsically perfect verbs do not take this marker, unless the perfectivity is emphasized.
Infinitives do not form perfectives by agglutination, but rather as phrases consisting of two infinitives, with the second infinitive being 'modan', which never appears in any inflected form (since it has been subsumed into the morphology of the finite verb.)
After stops, this mutates into
-wUksA-, where if U = u, the w- further vanishes.
The -m(closed vowel)- part of these morphemes comes from a particle, 'mod', which was a reduction of the verb 'took' and came to signify perfectiveness. -ksA- comes from a similar particle, 'okta', which signified 'maybe'. The optative perfect is always intransitive. If the verb usually would be transitive, the perfect optative is understood as a passive.
If followed by a morpheme beginning in a labial, this turns into -OlwO-.
The historical origin is a noun olob, signifying 'circumstance, case, chance, fate'.
From the imperative form of the verb 'go'. The marker that exists in other related languages had been lost, and the auxiliary 'go!' slowly was merged into the verb morphology. Certain verbs have their own exceptional forms.
The dubitative marks things that are somewhat unsure. The historical origin is a suffix -EŋdzE, whose further origins probably lie in an assimilated auxiliary. The suffix now is -ŋŋE
