korteihin

Korteihin is a Finnish grammatical form rather than a widely used concept on its own. It is the illative plural form of the noun korte, a term that can refer to the lower leg region—the area of the leg between the knee and the ankle—with emphasis often on the shin. In Finnish, the illative case marks movement toward or into something, so korteihin is used when describing actions, directions, or conditions affecting the lower legs in a plural sense.

Etymology and usage context: The base word korte is a native Finnish term with colloquial and regional usage. The illative plural suffix -iin combines with the stem korte- to produce korteihin. In contemporary standard Finnish, the more anatomically precise term for the lower leg is sääri; korte may appear in casual speech, dialects, or specific medical or athletic contexts where speakers refer to compounds or conditions involving the shin or lower leg.

Anatomy note: In medical language, the lower leg comprises bones such as the tibia and fibula, and muscles including the gastrocnemius and soleus. The use of korteihin is thus often stylistic or regional rather than a formal anatomical label. Phrases such as korteihin kohdistuva hoito (treatment directed at the lower legs) or korteihin liittyvät kivut (lower-leg-related pains) illustrate its practical usage in everyday or semi-specialized discourse.
