reiällä

reiällä is the adessive singular form of the Finnish noun reikä, meaning hole, opening, or perforation. It is a grammatical form, not a separate word with its own meaning, and it is used to express location in relation to a hole or to a surface that bears a hole.

Usage in Finnish follows the general rule that the adessive case marks location on or at something. Reiällä denotes position on top of or at the hole and is commonly found in descriptive or technical language describing objects with holes or features of a surface that include a hole. It often appears in manuals, diagrams, or inventories where locations are specified with respect to holes or openings.
