Tuntuihin

Tuntuihin is a Finnish inflected form that appears in linguistic discussions as an illative plural. It is not a standalone lemma in common usage, but rather a morphological variant formed from a stem related to the idea of feeling, sensation, or related abstract concepts. The illative case in Finnish expresses motion into or toward something, and the plural illative suffixes commonly surface as -iin or -ihin, depending on the stem’s vowel harmony.

The form tuntuihin illustrates how the illative plural can attach to a stem that carries a notion of sensation or experience. In practice, the exact base noun behind tuntuihin is often analyzed rather than spoken as a frequent word in everyday language. Because Finnish vowel harmony governs which illative plural variant appears, tuntuihin exemplifies the broader pattern of phonological alternation that occurs with the illative plural in many stems.

Usage and frequency are modest in contemporary speech. Tuntuihin is more likely to be encountered in grammar descriptions, linguistic research, or older literary texts than in daily conversation. When learners study the Finnish illative plural, tuned attention to forms like tuntuihin helps illustrate the mechanism of adding directional plural endings to stem bases.
