Iliajn

Iliajn is a grammatical form in Esperanto, serving as the accusative plural form of the possessive determiner ilia, meaning “their.” In Esperanto, adjectives and possessive determiners decline for number and case to agree with the noun they modify, and the accusative is marked by the ending -n. Therefore iliajn appears before a noun that is the direct object or otherwise in the accusative case.

Usage examples illustrate its function. Mi vidas iliajn domojn means “I see their houses,” with domojn in the accusative plural. Li renkontis iliajn amikojn means “He met their friends,” with amikojn in the accusative plural. In both cases iliajn indicates possession by a plural third party, and the following noun is marked for number and case accordingly.

Notes and context. Iliajn is not a standalone lexical item with a separate meaning beyond “their” in the accusative plural; it is a derived form used to modify a noun. Its use is confined to contexts requiring an explicit object marked by the accusative case.
