naapuriensa

Naapuriensa is a Finnish noun form built from the word naapuri (neighbor) with the third-person plural possessive suffix. In Finnish, possession is shown by attaching possessive endings to the possessed noun, and -nsä (with variants -nsä/-nsa depending on phonology) marks possession by they. The result naapuriensa expresses that something belongs to their neighbors or, in some contexts, to their neighbor collectively, with the exact sense guided by context and number.

The form is commonly used in everyday Finnish to indicate ownership in discussions about neighbors. It appears in phrases such as naapuriensa lapset (their neighbours’ children) or naapuriensa talo (their neighbours’ house). The possessed noun itself is declined according to Finnish grammar, while the possessor information is encoded in the suffix.

Etymology and morphology: naapuriensa is derived from naapuri plus the third-person plural possessive ending. The suffix shows who possesses the object, while the base noun can be singular or plural depending on what is being possessed in the sentence. Finnish possessive suffixes display vowel harmony and interact with the surrounding phonology, which is reflected in the exact spelling of the suffix.

Usage notes: As with other Finnish possessive forms, naapuriensa concentrates information about ownership into a single word, reducing the need for explicit possessive pronouns. In writing and speech, it commonly appears in narratives about neighbours and community relations.
