Jäsenseen

Jäsenseen is a form occasionally encountered in discussions of Finnish grammar as a nonstandard or archaic illative form of the noun jäsen, which means member. It is not used in contemporary standard Finnish, where the illative singular is usually jäseneseen. The appearance of jäsenseen is typically described in linguistic notes as a dialectal or historical variant, rather than as a characteristic of modern written Finnish.

In linguistic terms, jäsenseen would be analyzed as an illative form derived from the stem jäsen with an illative ending. Its usage in actual speech or texts is rare and confined to dialectal rediscoveries or older documents. Because it does not align with standard contemporary usage, jäsenseen is generally treated as obsolete or nonstandard for most language-learning and formal writing purposes.

Usage and guidance: In teaching, editing, and formal writing, prefer jäseneseen when expressing the illative “to/into a member.” If jäsenseen appears in a source, it is usually best understood as a regional, historical, or stylistic variant rather than as a normative form.
