First aorist endings

Most of the active and middle forms of the first aorist are similar to the forms of the present, except with an α in the endings instead of an ο or ε. The first person singular indicative active, second person singular imperfect middle, the second person singular imperatives, active infinitive, and masculine nominative singular of the participle (bolded), however, differ, and the subjunctive active and middle of the first aorist have endings identical to the present ones.

Most of the passive forms of the first aorist have endings similar to those of the root aorist.

The roots of the reconstructed Proto-Indo-European language are basic parts of words that carry a lexical meaning, so-called morphemes.

Root

The root aorist is characteristic of athematic verbs (those with a present active in -μι). Like the second aorist, the stem is the bare root, and endings are similar to the imperfect in the indicative, and identical to the present in non-indicative moods. It is sometimes included as a subcategory of the second aorist because of these similarities, but unlike the second aorist of thematic verbs, it has no thematic .

The singular aorist indicative active of some athematic verbs (τίθημι, ἔθηκα; δίδωμι, ἔδωκα) uses a stem formed by the suffix -κα and takes first aorist rather than root aorist endings.

Syntax

The aorist generally presents a situation as an undivided whole, also known as the perfective aspect
Perfective aspect
The perfective aspect , sometimes called the aoristic aspect, is a grammatical aspect used to describe a situation viewed as a simple whole, whether that situation occurs in the past, present, or future. The perfective aspect is equivalent to the aspectual component of past perfective forms...

.

Indicative mood

The aorist usually implies a past event in the indicative, but it does not assert pastness, and can be used of present or future events.
  • ἀπωλόμην ἄρ᾽, εἴ με δὴ λείψεις, γύναι.
I am undone if you will leave me, wife.

Narrative

The aorist and the imperfect are the standard tenses for telling a story. The ordinary distinction between them is between an action considered as a single undivided event and the action as a continuous event. Thus, for example, a process as a whole can be described in the imperfect, while the individual steps in that process will be aorist.
  • ἔπαιζε ἐν τῇ κώμῃ ταύτῃ ... μετ᾽ ἄλλων ἡλίκων ἐν ὁδῷ. καὶ οἱ παῖδες παίζοντες εἵλοντο ἑωυτῶν βασιλέα εἶναι... ὁ δὲ αὐτῶν διέταξε τοὺς μὲν οἰκίας οἰκοδομέειν, τοὺς δὲ δορυφόρους εἶναι, τὸν δέ κου τινὰ αὐτῶν ὀφθαλμὸν βασιλέος εἶναι, τῷ δὲ τινὶ τὰς ἀγγελίας φέρειν ἐδίδου γέρας,...
    [Cyrus] was playing in this village... in the road with others of his age. The boys while playing chose to be their king this one.... Then he assigned some of them to the building of houses, some to be his bodyguard, one doubtless to be the King's Eye; to another he gave the right of bringing him messages;....
Here the imperfect ἔπαιζε "was playing" is the whole process of the game (which continues past these extracts); the aorists the individual steps.


The narrative aorist has the same force, of an undivided or single action, when used by itself:
  • ἐπεὶ δὲ εἶδον αὐτὸν οἵπερ πρόσθεν προσεκύνουν, καὶ τότε προσεκύνησαν, καίπερ εἰδότες ὅτι ἐπὶ θάνατον ἄγοιτο.
    And when the men who in former days were wont to do him homage saw him, they made their obeisance even then, although they knew that he was being led forth to death.
Were wont to do him homage is the imperfect, made their obeisance the aorist, of προσκύνω "kowtow".

Complexive

On the other hand, if the entire action is expressed, not as a continuous action, but as a single undivided event, the aorist is used:

Herodotus introduces his story of Cyrus playing with:
  • καὶ ὅτε ἦν δεκαέτης ὁ παῖς, πρῆγμα ἐς αὑτὸν τοιόνδε γενόμενον ἐξέφηνέ μιν·​
    Now when the boy was ten years old, the truth about him was revealed in some such way as this:


The aorist is also used when something is described as happening for some definite interval of time; this particular function can be more precisely called the temporal aorist:
  • Οὑμὸς πατὴρ Κέφαλος ἐπείσθη μὲν ὑπὸ Περικλέους εἰς ταύτην γῆν ἀφικέσθαι, ἔτη δὲ τριάκοντα ᾤκησε.
    My father Cephalus was persuaded by Pericles to come to this land and lived (there) thirty years.

     4

Past-in-the-past

The other chief narrative use of the aorist is to express events before the time of the story:
  • τούς τε Ἱμεραίους ἔπεισαν ξυμπολεμεῖν καὶ αὐτούς τε ἕπεσθαι καὶ τοῖς ἐκ τῶν νεῶν τῶν σφετέρων ναύταις ὅσοι μὴ εἶχον ὅπλα παρασχεῖν (τὰς γὰρ ναῦς ἀνείλκυσαν ἐν Ἱμέρᾳ)
    they persuaded the Himeraeans to join in the war, and not only to go with them themselves but to provide arms for the seamen from their vessels (for they had beached their ships at Himera)

Ingressive

In verbs denoting a state
Stative verb
A stative verb is one that asserts that one of its arguments has a particular property . Statives differ from other aspectual classes of verbs in that they are static; that is, they have undefined duration...

 or continuing action, the aorist may express the beginning of the action or the entrance into the state. This is called ingressive aorist (also inceptive or inchoative).
  • βασιλεύω "I am king" (present) — ἐβασίλευσα "I became king" or "I ruled" (aorist)
    basileúōebasíleusa

Resultative

The resultative aorist expresses the result of an action. Whether this is truly distinguishable from the normal force of the narrative aorist is disputable.
  • ἐβούλευον "I was deliberating" is imperfect; ἐβούλευσα "I decided" is aorist.

Gnomic

The gnomic aorist expresses the way things generally happen, as in proverbs. The empiric aorist states a fact of experience (ἐμπειρίᾱ empeiríā), and is modified by the adverbs often, always, sometimes, already, not yet, never, etc. (English tends to express similar timeless assertions with the simple present.)

The gnomic aorist is regarded as a primary tense

), or, according to another analysis, a state of mind. This is called tragic or dramatic aorist. The aorist is used when the action is complete in the single statement; the present when the speaker goes on to explain how or why he is acting.
  • Ἀλλαντοπώλης. ἥσθην ἀπειλαῖς, ἐγέλασα ψολοκομπίαις,
    ἀπεπυδάρισα μόθωνα, περιεκόκκασα.
    Sausage-seller. I like your threats, laugh at your empty bluster,
    dance a fling, and cry cuckoo all around.
: translated by William James Hickie

Unattainable wish

A wish about the past that cannot be fulfilled is expressed by the aorist indicative with the particles
Grammatical particle
In grammar, a particle is a function word that does not belong to any of the inflected grammatical word classes . It is a catch-all term for a heterogeneous set of words and terms that lack a precise lexical definition...

 εἴθε or εἰ γάρ "if only" (eíthe, ei gár). This is called the aorist of unattainable wish.
  • εἴθε σοι, ὦ Περίκλεις, τότε συνεγενόμην.
    If only I had been with you then, Pericles!


An unattainable wish about the present uses the imperfect. A wish about the future uses the optative with or without a particle; an optative of wish may be unattainable.

Non-indicative moods

Outside of the indicative mood, sometimes the aorist determines time (often past time), and sometimes the function of the mood determines it. When the aorist does not determine time, it determines aspect instead.

Aorist in indirect discourse refers to past time relative to the main verb, since it replaces an aorist indicative.

An imperative, subjunctive or optative in an independent clause usually refers to future time, because the imperative express a command, the subjunctive expresses urging, prohibition, or deliberation, and the optative expresses a wish or possibility.
