leirillä

Leirillä is a Finnish locative form of the noun leiri, meaning camp. It is the adessive singular form and is used to express location or presence at a camp, often translated as "at the camp" or "in camp." The word leiri refers to a temporary settlement used for camping, such as youth camps, scout camps, military training camps, or refugee camps, as well as more general camping areas.

In usage, leirillä appears in sentences that describe where an action takes place or where someone is staying. Examples include: "Olen leirillä kolme viikkoa" (I am at the camp for three weeks), "Leirillä on paljon telttoja" (There are many tents at the camp), and "Lapset asuvat leirillä" (The children live at the camp). The form is commonly used in everyday Finnish when talking about organized camps or temporary settlements.

Leiri has related grammatical forms that express other locational meanings: leirissä (inessive, "in the camp"), leiriltä (elative, "from the camp"), leirille (illative, "into the camp"), and so on. These forms are part of Finnish case morphology and are chosen according to the syntactic relationship described by the verb or preposition.

Etymology and usage context: leiri is of Finnish origin, with cognates in related Nordic languages; the concept and word are closely tied to organized group camping activities, including youth and scout contexts. The term also appears in place names and compound forms like leirikeskus (camp center) or leirialue (camping area). In contemporary Finnish, leirillä remains a common way to specify the location of activities tied to camps.
