Jälkeläisillä

Jälkeläisillä is the adessive plural form of the Finnish noun jälkeläiset, meaning descendants or offspring. It is used to indicate that the descendants are in a certain relation or possession in a sentence, for example with the verb olla (to have): "jälkeläisillä on oikeus" meaning "the descendants have the right." The base word jälkeläiset refers to people who are descended from a common ancestor or lineage, including successive generations.

In practice, jälkeläisillä appears frequently in legal, genealogical, and historical contexts. In inheritance and family law it can mark who possesses a right or claim, as in will or estate discussions. In genealogical writing it helps identify members of a family line and their place in the lineage. The term can also appear in historical or biographical texts when describing the descendants of a notable person.

Grammar notes: jälkeläillä is the adessive plural form; other forms of the same word include jälkeläiset (nominative plural), jälkeläisiä (partitive plural), and jälkeläisten (genitive plural). The choice of case signals the role of the descendants in the sentence—possession, location, or relation—rather than indicating the number of generations themselves.
