jälkeläisillään

Jälkeläisillään is a Finnish word that translates to "with their offspring" or "by their descendants." It is a grammatical form used in the Finnish language to indicate possession or agency related to one's progeny. This term is typically used in contexts discussing lineage, inheritance, or the continuation of a family or species.

In Finnish grammar, the suffix "-llään" indicates the possessive suffix for the third-person plural, referring to "their." When combined with "jälkeläinen," which means "offspring" or "descendant," it forms "jälkeläisillään." This construction implies that the offspring themselves possess something, or that something is being done by or through them.

For example, one might say a family is known for its scientific contributions, and that these contributions are continued "jälkeläisillään." This would mean that their descendants are also contributing to science. Another context could be an animal species that is thriving due to the successful reproduction and care of its young, "jälkeläisillään" indicating the species' success through its offspring. The specific meaning can vary slightly depending on the sentence structure and surrounding words, but the core idea of connection to descendants remains.
