Intensiiviseen

Intensiiviseen is the illative singular form of the Finnish adjective intensiivinen, meaning intensive. In Finnish, illative forms are used to express movement toward or direction into something, and intensiiviseen is used when the noun it modifies is in the illative case.

The form is most common in contexts describing programs, courses, or activities that are characterized by a high level of focus or pace. For example, intensiiviseen kurssiin means “to an intensive course,” and intensiiviseen opetukseen can mean “to intensive instruction.” These phrases typically occur with verbs of movement or participation, such as mennä, osallistua, siirtyä, or hakeutua.

Usage notes help distinguish intensiiviseen from other cases of the same adjective. The nominative form intensiivinen modifies a noun in the base form (e.g., intensiivinen kurssi, “an intensive course”), while intensiiviseen is chosen when the noun phrase is in illative. The phrase intensiiviseen kurssiin is a common construction in education, training, and organizational contexts to convey a concentrated or accelerated program.

Etymology-wise, intensiivinen is borrowed from the word intensive, with its Finnish form adapted to fit Finnish inflectional patterns. The illative form intensiiviseen reflects typical suffixing for adjectives in -inen when combined with illative case.
