loppulukuihin

Loppulukuihin is a Finnish term formed from loppu meaning “end” and luku meaning “number,” with the illative plural suffix -iin or -ihin, yielding a literal meaning roughly “to the ending numbers.” It is not a standard technical term in Finnish mathematics or grammar, and its use tends to be limited to explanatory or pedagogical contexts where a concrete phrase is needed to illustrate inflection or a concept tied to the notion of endings.

In linguistic or grammatic discussions, loppulukuihin can be described as an example of how Finnish nouns in compounds take case endings in plural and evolve when linked to other words, rather than as a fixed vocabulary item with a single, widely accepted definition. Because the phrase is not common in ordinary Finnish, its precise interpretation depends on context, and it may be encountered mainly in language-education materials or descriptive text about word formation.

In mathematical or numerical contexts, if used, the expression is typically interpreted informally as referring to the digits at the end of a number (for example, the last digits obtained when considering a base representation or a modulus). However, this usage is descriptive rather than standard terminology, and speakers usually prefer terms such as “the trailing digits” or “the final digits.”
