aukkoon

Aukkoon is the illative case form of the Finnish noun aukko, which means a hole, opening, or gap. The illative marks direction or motion into a location, and it is commonly used to describe entering a hollow space or moving toward an opening. In Finnish, many nouns change form to express different grammatical cases, and aukko follows this pattern with distinct singular and plural forms.

Key forms of aukko:

- Nominative singular: aukko

- Genitive singular: aukon

- Illative singular: aukkoon

- Partitive singular: aukkoa

- Nominative plural: aukot

- Genitive plural: aukkojen

- Illative plural: aukkoihin

- Partitive plural: aukkoja

Usage notes:

- The illative aukkoon is typically used with verbs of motion or perception that convey entering or moving toward an opening. For example, "Hän putoaa aukkoon" means “He/She falls into a hole,” illustrating motion into the space.

- Aukko is a native Finnish noun, and its case forms are part of standard Finnish grammar. Illative forms like aukkoon are distinct from the genitive form aukon, which denotes possession or a related relationship (e.g., “the hole’s edge” or “the edge of the hole” depending on context).

Examples:

- Hän putoaa aukkoon. (He falls into a hole.)

- Kissa kurkisti aukkoon ja näki valon. (The cat peered into the opening and saw light.)

Aukkoon, as a grammatical form, exemplifies Finnish case-based morphology, where the ending conveys the relational meaning of entering or moving toward an opening.
