numeroille

Numeroille is the allative form of the Finnish noun numero. In Finnish, numero means “number” and is a loanword from Latin or Italian. The allative case formed with -ille marks direction toward or recipient of something, and can indicate “to the numbers” or “for the numbers.” This form is mainly encountered in linguistic or technical contexts rather than everyday speech.

Usage of numeroille is typical in discussions about numbering systems, data organization, indexing, or labeling where numbers themselves are treated as the objects of an action. In written Finnish, numeroille appears in grammars, dictionaries, or mathematical texts as an example of case inflection and as part of discussions about the use of Finnish cases with loanwords.

Examples include sentences such as taulukko on jaettu numeroille 1–10 (the table is divided for the numbers 1–10) and merkitse rivit numeroille 1–10 (mark the rows for numbers 1–10). The form behaves like other -ille allative endings such as taloille (to the houses) and is used regardless of whether the reference is to a single number or multiple numbers, depending on context. Overall, numeroille serves as a specific inflected form useful for technical or linguistic purposes rather than common everyday expression.
