Hermosoluun

Hermosoluun is the illative form of the Finnish noun hermosolu, meaning “into the neuron” or “to the neuron.” It is used to express direction or movement toward a nerve cell and appears in sentences describing processes that involve entering or acting upon a neuron.

Formation and grammar: The base word hermosolu combines hermo (nerve) and solu (cell). The illative suffix -uun marks direction toward something; the complete form is hermosoluun. This suffix is one of the Finnish location/motion cases and follows standard phonological rules for noun stems ending in -olu.

Usage notes: In everyday Finnish, hermosoluun is most common in scientific, educational, or descriptive contexts about neural processes. It is not a separate scientific term by itself; the biological term for the cell is hermosolu, while hermosoluun is a grammatical form used to indicate movement or action directed at the neuron. A typical usage is in phrases such as “signaali kulkee hermosoluun,” meaning a signal travels into the neuron.
