vaarallista

Vaarallista is a Finnish word that functions as the partitive singular form of the adjective vaarallinen, meaning dangerous. It is used to express danger in statements about actions or situations and appears in predicative constructions and phrases involving an infinitive.

In Finnish, adjectives decline for case and number. The base form is vaarallinen (nominative). The partitive singular form vaarallista is used in several contexts, notably with infinitival clauses or with verbs that require a partitive complement, and in some constructions with indefiniteness or general statements about risk.

Common uses include phrases such as to do something is dangerous: Tehdä näin on vaarallista. This illustrates how the infinitive clause can be linked to the adjective in its partitive form. Another use is the exclamatory or admonitory sense, where vaarallista appears on its own as an interjection equivalent to “Danger!” or “This is dangerous.” In longer sentences, vaarallista can modify a noun phrase indirectly, for example: Tämän tehtävän suorittaminen on vaarallista, meaning “The completion of this task is dangerous.”

Etymology and related forms: vaarallista derives from the adjective vaarallinen, which in turn is connected to the noun vaara (danger). Related forms include the nominative vaarallinen and the other cases of the adjective, as well as the noun vaara used to name danger itself.
