Hajottavan

Hajottavan is the genitive singular form of the Finnish present active participle hajottava, which comes from the verb hajottaa meaning "to decompose" or "to break down." In Finnish grammar, the present active participle functions as an adjective and can be declined to agree with the noun it modifies. When the participle appears in a genitive phrase, the form hajottavan is used, as in hajottavan aineen ominaisuudet, meaning "the properties of the decomposing substance."

Usage and context: The form hajottavan is most common in technical or descriptive texts that discuss decomposition processes, such as biology, environmental science, waste management, and soil science. It communicates ongoing action and processes rather than finished states, emphasizing the nature of decomposition.

Morphology and notes: Hajottava follows the Finnish participle pattern with the suffix -va/-vä, adjusted for vowel harmony. The genitive singular form hajottavan arises when the participle modifies a head noun in genitive or appears within a genitive construction. As a grammatical form, hajottavan is not a separate lexical item but a case-inflected version of hajottava used in adjective-like function.

In summary, hajottavan is a Finnish grammatical form used to describe something that is decomposing, occurring within noun phrases that require a genitive articulation, particularly in scientific and technical writing.
