Nilkkoihin

Nilkkoihin is the illative plural form of nilkka, the Finnish word for ankle. In Finnish, the illative case marks direction toward a place or endpoint of motion; nilkkoihin therefore means “to the ankles” or “into the ankles.” It is used when the destination or boundary involves the ankle region, for example in descriptions of clothing, water, or body position, rather than as an independent noun.

Morphology: It is formed from the stem nilkka with the plural illative suffix -iin (commonly realized as -koihin after certain consonant stems). The form reflects standard Finnish noun inflection rules, and is spelled as nilkkoihin with the double k preserved and the vowel harmony maintained.

Usage: In ordinary speech, nilkkoihin occurs mainly in contexts describing movement toward or ending at the ankles or describing proximity to the ankles. It is infrequently used outside such contexts. In literature or technical descriptions (e.g., anatomy, clothing design), you may encounter nilkkoihin to specify extent or reach.

Examples:

- Vesi nousi nilkkoihin asti. (The water rose up to the ankles.)

- Saappaat puristivat nilkkoihin. (The boots pressed against the ankles.)

Notes: Nilkkoihin is not a separate lexical entry with a meaning like a place or concept; it is a grammatical form. The base word nilkka is the anatomical term for the ankle.
