rakoihin

Rakoihin is a Finnish word-form that functions as the illative plural of the noun rako, meaning gaps, openings, or cracks. In Finnish grammar, the illative case marks movement into something; rakoihin literally conveys entering into gaps or openings. The base noun rako denotes a physical or figurative space between surfaces, and rakoihin is formed by adding the illative plural suffix -iin to the stem rako, following standard harmony rules.

Etymology and form: Rako is a native Finnish noun, and the illative plural suffix -iin is a common Finnic ending used to express direction into multiple referents. The combination yields rakoihin, pronounced with the stress on the first syllable.

Usage: Rakoihin appears in descriptive or literary Finnish to describe entering or moving into gaps, crevices, or spaces. It can be used literally (into physical gaps) or metaphorically (into spaces between ideas or arguments). It is not a proper noun or a specialized technical term outside ordinary Finnish grammar.
