Kartoihin

Kartoihin is a Finnish word that functions as the illative plural form of kartta, meaning “into maps” or “to maps.” It is used in expressions that indicate movement toward multiple maps or when maps are the target of an action. The form is commonly found in texts related to geography, cartography, and geographic information systems (GIS).

Morphology and grammar: In Finnish, the illative case marks direction toward a destination. The plural illative suffix attached to the stem kartto- yields kartoihin. By contrast, the singular illative form is karttaan. The choice between these forms depends on whether the reference is to one map or several maps, and on the verb’s valency and case requirements.

Common usages: kartoihin appears frequently in technical and educational writing about mapping, GIS data processing, and map-based analyses. It can appear in phrases such as kartoihin liittyvä data, kartoihin tehtävät merkinnät, or data transferred to maps. In everyday Finnish, more common constructions may use other cases, but kartoihin remains a standard form for the plural illative when referring to movement toward or placement into multiple maps.

Etymology and related terms: kartoihin is formed from kartta (map) with the illative plural suffix. Related terms include kartta (singular map) and kartat (plural maps). The illative is one of several case forms used in Finnish to express direction and destination in conjunction with nouns like kartta.
