The injunctive mood was a mood in Sanskrit characterized by secondary endings but no augment, and usually looked like an augmentless aorist or imperfect. It typically stood in a main clause and had a subjunctive or imperative meaning; for example, it could indicate intention, e.g. índrasya nú vīryā̀ṇi prá vocam "Indra's heroic deeds will/shall I now declaim" (Beekes 1995). It was obligatory for use in prohibitions, where it follows mā́. In later Classical Sanskrit, only the use after mā remained (there were no accents in Classical Sanskrit).

Ancient Greek has words that are formally similar to the Sanskrit injunctive mood, consisting of aorist and imperfect forms lacking the augment. However, in this case there is no difference in meaning between these forms and the normal augmented forms. These are normally used in Homeric Greek and in epic poetry (Epic Greek). Ancient Greek refers to the stage in the history of the Greek language corresponding to Classical Antiquity, which normally applies on two ancient periods of Greek history: Archaic and Classic Greece. ...

It is generally assumed that the augment was originally a separate participle meaning something like "then", added to indicate the past time of a form that was once mostly aspectual, and neutral with respect to tense. Originally, its use appears to have been optional, added as necessary to clear up an otherwise ambiguous expression, similarly to time adverbs in Chinese. Gradually, it fused onto the verb form and became mandatory, but in the early stages of Greek and Sanskrit this change was not yet complete, and hence augmentless forms existed side-by-side with augmented forms. The modal semantics of the augmentless forms may then be a later development within Indo-Iranian or Indo-Aryan. It's also possible that the modal semantics developed in the parent language and later developments in Pre-Greek removed them and put back the basic meaning of the aorist and imperative, by analogy. (This hypothesis, however, contradicts Occam's Razor.) In linguistics, grammatical aspect is a property of a verb that defines the nature of temporal flow (or lack thereof) in the described event or state. ...
