Merialueisiin

Merialueisiin is the illative plural form of the Finnish noun merialue, which refers to marine areas—sections of the sea that are relevant for jurisdiction, planning, or study. In Finnish, the illative case expresses direction toward or into something, and merialueisiin is formed from merialueet (the marine areas) plus the illative suffix -iin. Therefore, merialueisiin is used when stating movement toward those areas or describing effects or actions that involve them.

Usage and contexts

The term appears frequently in official texts and professional contexts such as maritime planning, environmental protection, fisheries management, and coastal development. It can function as the object of verbs that express movement, impact, or involvement, for example in policy documents or research reports that address management of sea zones.

Examples

Hankkeen vaikutukset ulottuvat merialueisiin. (The project’s effects extend to the marine areas.)

Tutkimus käsittelee merialueisiin liittyviä haasteita. (The study deals with challenges related to the marine areas.)

Linguistic notes

Merialueisiin exemplifies Finnish noun inflection, where illative plural marks direction toward multiple marine areas. This form is user-facing in contexts dealing with geography, governance, or science and is distinct from the nominative merialueet or other cases such as merialueisiin kuuluvat (things that pertain to the marine areas).
