Oni = one, people, they, we (like the French "on"), is an indefinite pronoun of the 3rd person. Oni may be deemed singular or plural.
Owing to the fact that in most languages the word corresponding to oni is invariable, Esperanto authors have generally avoided the accusative and possessive forms onin and onia, although they are occasionally met with. These forms are, however, perfectly regular, and may be used without hesitation if desired.
Si = self, selves, oneself, is a reflexive pronoun of the 3rd person, singular or plural.
Vi, like "you" in English, represents both the singular and plural, but when it refers to more than one person, words depending on it take the plural form.
Ĝi, like "it" in English, is used to represent things, and also persons and animals when the name does not reveal the sex.
Examples.—Mi lin amas = I love him. Li min vidas = He sees me. Ili trovis lin kaj min en la ĝardeno = They found him and me in the garden. Vi ne vidis nin = You did not see us. Vi (plural) estas pli saĝaj, ol ili (estas) = You are wiser than they are. Ŝi vidis ilin en la dormoĉambro = She saw them in the bedroom. Oni diras, "Per mono oni povas aĉeti ĉion" = They (people) say (it is said), "With money one (or, we) can buy everything. Mi vidis la domon, sed ĝi estis tro malgranda = I saw the house, but it was too small. Se oni estus riĉa, or riĉaj = If one were rich.
