Adverbiivien

Adverbiivien, in Finnish grammar, refer to adverbial participles, a class of non-finite verb forms that function as adverbs within a sentence. They provide circumstantial information about the action of the main verb or clause, such as time, manner, place, cause, or condition, and they can link additional information to the main clause without forming a separate subordinate sentence.

The most common forms are present adverbial participles, created from the verb stem with participial endings. Typical examples include katsoen (looking) and tehden (doing). Some adverbiivien constructions can carry a possessive suffix to indicate the subject of the adverbial action, for instance mennessäni (while I was going). Adverbiivien may occur on their own in a sentence or be paired with other elements to express more complex circumstances.

Functionally, adverbiivien modify the action of the main verb or the whole clause, and they can sometimes substitute for a subordinate clause, yielding a more compact sentence. In written Finnish, they are most common in literary or formal styles and are often set apart by a comma when they appear in the main clause.

Usage considerations include register and clarity. Adverbiivien offer a concise way to convey circumstantial information, but in everyday speech they are less frequent and other constructions (such as subordinate clauses or adverbs) may be preferred for ease of understanding. The concept of adverbiivien aligns with the broader cross-linguistic idea of adverbial participles—non-finite verb forms that function adverbially to describe how, when, or why an action occurs.
