sisäänkäyntiin

Sisäänkäyntiin is the illative singular form of the Finnish noun sisäänkäynti, which means “entrance” or “entry” of a building. The illative case is used in Finnish to indicate movement toward the inside of a place and is commonly attached to a noun to express “to the …” or “into the …” when describing direction.

Form and usage: The base noun sisäänkäynti refers to the entrance itself. To express movement toward that point, the illative suffix -iin is added, yielding sisäänkäyntiin. It is typically used with verbs of motion or direction, such as mennä (to go), tulla (to come), or kulkea (to move). Examples: Mennään sisäänkäyntiin. Portaat johtavat sisäänkäyntiin. In many everyday contexts, however, the entrance is simply called sisäänkäynti on signage and addresses, with sisäänkäyntiin used when a specific directional meaning is intended in a sentence.

Etymology and forms: The word is a compound of sisään ('into') and käynti ('going, entry'), with the illative suffix -iin forming a phrase that denotes movement toward the location. Related forms include sisäänkäynti (nominative), sisäänkäynnin (genitive), and sisäänkäyntiin (illative).

See also: The term is closely related to other directional cases in Finnish grammar and to everyday signs indicating entrances, such as “Sisäänkäynti” on doors and buildings.
