teräkseen
Teräkseen is a Finnish word form that functions as the illative case of the noun teräs, meaning steel. In Finnish, the illative expresses motion into or toward something, so teräkseen can be understood literally as “into steel” and, in figurative contexts, as a movement toward a state associated with steel, such as strength or resilience. The form is primarily found in literary, historical, or technical writing and is not common in everyday speech.

Usage: Teräkseen is relatively rare in contemporary, ordinary Finnish. It appears mainly in poetry, historical narration,
