Perheenjäseniin

Perheenjäseniin is a Finnish grammatical form meaning “to the family members” or “into the family members.” It is the illative plural form of perheenjäsen, which itself means a member of a family. The illative case denotes direction toward something or into a location, so perheenjäseniin is used when the action is directed at the family members as a group or when describing movement toward them in a sentence.

Morphology and related forms help clarify its use. The base noun is perheenjäsen (family member). In the plural nominative it becomes perheenjäsenet (the family members). The illative plural, formed with the suffix -iin, yields perheenjäseniin. Other common plural forms of perheenjäsen include the partitive perheenjäseniä (some family members) and the genitive perheenjäsenten (of the family members). These forms reflect Finnish’s rich case system and the way meaning shifts with different endings.

Usage considerations are important. The illative plural is a specific, sometimes formal, way to indicate direction toward a group of people. In everyday prose or speech, speakers may choose other constructions, such as the allative form perheenjäsenille to express “to the family members” when indicating recipients or beneficiaries of an action, or using a different case to fit the verb or preposition in the sentence. Perheenjäseniin appears most readily in contexts that require a precise illative destination toward the family members as a collective.

In summary, perheenjäseniin is the illative plural form of perheenjäsen, used to express direction toward the family members and is one option among several case forms to convey related meanings.
