From these verbal nouns, denominative verbs could be made; thus from zicu plus -ce, a past tense of perfective affix, was made zichuche "he wrote, he has written".
The verb is inflected for mood (indicative, subjunctive, imperative), aspect (perfective, imperfective), voice (active, passive), tense (present, past), and person (first, second, and third, singular and plural).
Only the present and future indicative forms are fully conjugated in Hindi, while other tenses are indicated with the help of perfective and imperfective participles combined with the auxiliary verbs.
Perfective done usually precedes an eventive verb with a past tense form, such as the -ed suffix (Green 2002), as in (2a).
Most Nahuatl dialects distinguish three tenses: present, past, and future, and two aspects: perfective and imperfective.
It has two numbers, two genders, three moods, three cases (subject, oblique, and vocative), three persons, and five tenses (present, imperfect, perfect, pluperfect, and future, grouped into two aspectual conjugations, the "present" and the "perfective").
The future is expressed by a particle tha (from earlier thé[o] na '[I] want to') followed by a finite verb e.g., tha grápho 'I will write.' Formally, the finite forms of the verb (those with personal endings) consist of a stem + (optionally) the perfective aspect marker (-s- in active, -th- in passive) + personal ending (indicating person, tense, mood, voice).
One may consider the possibility that it is quite common across languages for an (outer) aspect to develop tense-like behavior through certain syntactic mechanisms (e.g., the past construal of perfective aspects in British English and Taiwan Mandarin).
To mark such forms unambiguously as past indicatives, an augment, usually consisting of the vowel e, could be prefixed e.g., *é-gwhen-t 'he slew,' *é-H1es-t 'he was.' Verbs in the perfective aspect without a mood suffix did not occur with primary endings and thus lacked a true present tense.
