529.The Accusative is used mostly with verbs, but also with some adjectives and nouns and with certain prepositions.
530. The Accusative is used as the Direct (Outer) object of a transitive verb:
a. Many Greek verbs are transitive, requiring a preposition in the English translation.
Ἄρκτον ποτὲ ἐπιφερομένην οὐκ ἔτρεσεν.
A bear that once attacked him he did not shrink from.
Xen. Anabasis 1.9.6
οὐδὲ Δία ξένιον ᾐδέσθη.
He felt no shame even before Zeus, protector of the stranger.
Xen. Anabasis 3.2.4
to keep silent about my fortune
Aesch. Prometheus Bound 106
So, among many others, αἰσχῡ́νομαι (feel shame before) ὄμνῡμι (swear by), λανθάνω (escape the notice of; Latin lateo), εὖ or κακῶς ποιῶ (do good or harm to), φυλάττομαι (guard against), ἀμῡ́νομαι (defend myself against), πλέω τὴν θάλατταν (sail over the sea), φθάνω (get the start of).
b. Some intransitive verbs become transitive when compounded with certain prepositions, as διαβαίνω (cross) ἀποδιδρᾱ́σκω (run away from).
c. Many verbs vary, and are used now as transitive, now as intransitive. Thus ἀκούω (hear) and αἰσθάνομαι (perceive) take the accusative and genitive; μέμφομαι (blame) takes the accusative or the dative. Especially in poetry some verbs take the accusative that do not in prose.
531. A few verbal adjectives and nouns admit a direct object (as participles and infinitives of transitive verbs do regularly).
Ἐπιστήμονες τὰ προσήκοντα
knowing their duty
Xen. Cyropaedia. 3.3.9
able to escape thee
Soph. Antigone. 787
τὰ μετέωρα φροντιστής

a. A phrase may be equivalent to a transitive verb, and so take an accusative.
532. The Accusative is used after the particles of swearing, νή and μά, as with ὄμνῡμι (§ 530.a, above). νή affirms; μά denies, unless ναί (yes) precedes.
Nὴ Δία or ναὶ μὰ Δία
Yes, by Zeus.
533. In poetry the accusative may denote the limit of motion.
Ἥξεις Ὑβριστὴν ποταμὸν οὐ ψευδώνυμον.
Thou wilt come to the brawling stream, not falsely named.
Aesch. Prometheus Bound 717
σὲ τόδʼ ἐλήλυθε πᾶν κράτος.
To thee all this power has come.
Soph. Philoctetes 141–142
534. Two Accusatives denoting the same person or thing, the direct (outer) object and a predicate accusative, may stand with some verbs.
Κῦρον σατράπην ἐποίησε καὶ στρατηγὸν δὲ αὐτὸν ἀπέδειξε.
He made Cyrus satrap, and appoited him general also.
Xen. Anabasis 1.1.2
τοὺς ἰχθῦς οἱ Σύροι θεοὺς ἐνόμιζον.

Xen. Anabasis 1.4.9
a. These predicate accusatives shade off gradually into simple appositives; some cases may be taken in either way.
Ἔδωκα δωρειᾱ̀ν τὰ λύτρα.
I gave the ransom as a gift.
b. In the passive the direct object is made subject; the other accusative remains a predicate noun, agreeing with the subject.
535. Two Accusatives, one of the person and one of the thing (double outer object), are found with some verbs, especially those meaning ask, demand, teach, remind, hide, deprive.
Κῦρον αἰτεῖν πλοῖα
to ask Cyrus for boats
Xen. Anabasis 1.3.14
ἀναμνήσω ῡ̔μᾶς καὶ τοὺς τῶν προγόνων κινδῡ́νους.

a. A noun, with a modifying word or clause (rarely omitted).

Miletos never cared either much or little about these matters.
Plato Apology 26b
So τί χρήσεται τούτῳ; (what use will he make of this?), μέγα φρονεῖν (be proud, literally think large), πάντα πείθεσθαι (render all obedience), etc.
c. Some verbs take both a direct object and a cognate accusative.
Ἡμᾶς τὰ αἴσχιστα αἰκισάμενος
by inflicting on us the most shameful outrages
Xen. Anabasis 3.1.18
ἕκαστον εὐεργετεῖν τὴν μεγίστην εὐεργεσίᾱν

What wrong did you receive from me, that you are now scheming against me?
Xen. Anabasis 1.6.8

Here belong expressions like προῖκα (as a gift, freely), χάριν τινός (as a favor to [for the sake of] some one), τεκμήριον (as evidence), τὸ μέγιστον (as the chief point), τὸ λεγόμενον (as the saying is). When placed before the clause, such expressions may pass over into the use mentioned in § 491.d.
540.The Accusative in many expressions has become in effect an adverb. Such Adverbial Accusatives are special forms of the uses described in §§ 536 – 539 (above), we can not always say which. The following are rather frequent.
Tόνδε τὸν τρόπον
in this manner
τὴν ταχίστην (ὁδόν)
by the quickest road, most speedily
not at all
