larvaalisen

Larvaalisen is a Finnish adjective form meaning "of or relating to larvae." It is formed from the noun larva and the adjectival suffix -lainen, which is used in Finnish to create adjectives describing a relation, origin, or characteristic. In Finnish, adjectives inflect to agree with the noun they modify in case, number, and definiteness; larvaalisen is the genitive singular form of the adjective and appears when the noun it describes is in the genitive or when the phrase itself requires a genitive attribute. For example: larvaalisen kehityksen tutkimus—"the study of larval development"—uses larvaalisen in the genitive singular to modify kehitys (development) in genitive.

The term is primarily encountered in scientific, descriptive, or technical Finnish writing, especially in biology and zoology, where precise reference to larval stages is needed. It is not a standalone noun but a descriptor; other inflected forms of the same adjective are used to fit different grammatical contexts.
