Cf. the expression of purpose by the infinitive with por (98), which however cannot be used except when the subject of the main verb is the subject of the subordinate verb, or when the object of the main verb is the subject of the subordinate verb.
FURTHER USES OF THE ACCUSATIVE.
Cf. the accusative of direct object (23), direction of motion (46, 121), time (91), and measure (139).
263. The accusative of direction of motion is used after nouns from roots expressing motion:
Lia eniro en la urbon estis subita, his entrance into the city was sudden.
La irado tien estos plezuro, (the) going thither will be a pleasure.
Ĝia falado teren timigis min, its falling earthward terrified me.
264. a. An intransitive verb may be followed by a noun in the accusative case, if the meaning of the noun is related to that of the verb:
Li vivas agrablan vivon, he lives an agreeable life.
Ŝi dancis belan dancon, she danced a beautiful dance.
Ili ploris maldolĉajn larmojn, they wept bitter tears.
b. Verbs of motion (iri, veni, pasi, marŝi, veturi, etc.) compounded with prepositions or adverbs (121) indicating direction, also compounds of such verbs as esti and stari with prepositions expressing situation, may be followed by the accusative, instead of by a prepositional phrase in which the preposition is repeated:
La viro preterpasis la domon, the man passed (by) the house.
Lin antaŭvenis du sklavoj, there preceded (came before) him two slaves.
Ni supreniru la ŝtuparon, let us go up the stairs.
Mi ĉeestis la feston, I attended (was present at) the entertainment.
Mi kontraŭstaras vian opinion, I oppose (withstand) your opinion.
c. The slight change in meaning given by pri used as a prefix may render intransitive verbs transitive. The same is true of el prefixed to intransitive verbs not expressing motion:
