Parasiitteihin

Parasiitteihin is a Finnish grammatical form that serves as the illative plural of parasiitti, meaning parasites. The form is used to indicate direction toward or reference to multiple parasites, for example as the target of a treatment, a study, or an ecological interaction. In scientific and medical Finnish, parasiitteihin commonly appears in contexts where actions or analyses are directed at parasites, such as kohdistua parasiitteisiin (to be directed at parasites) or suunnata tutkimusta parasiitteihin (to direct research toward parasites).

Usage and examples help illustrate its function. For instance, Lääkkeet on suunnattu parasiitteihin shows a formulation where treatment is aimed at parasites, while Tutkimus keskittyy parasiitteihin kohdistuvaan vastetta discusses responses directed at parasites. Parasiitteihin liittyvät ilmiöt, kuten parasiittien epidemiologia ja ekologi, are routinely described with this illative plural to specify the parasite group under study or consideration.

Etymology and morphology. Parasiitteihin derives from parasiitti (parasite) plus the Finnish illative plural suffix -iin/-ihin, a common ending for indicating direction toward multiple entities. The form reflects Finnish case grammar rather than a standalone word with a separate meaning beyond its case-based function.
