tölulegir

Tölulegir is an Icelandic adjective meaning numerical or quantitative, relating to numbers rather than qualities. It is used to describe data, methods, or concepts that involve counting, measurement, or numerical values.

The word derives from the root for numbers (tala/tölu-) and the typical Icelandic adjective suffix -leikr, with the plural masculine form tölulegir. Like other Icelandic adjectives, tölulegur changes its ending to agree with gender, number, and case of the noun it modifies (for example, tölulegir menn, tölulegar gáttir, tölulegt gildi).

In usage, tölulegir is common in mathematics, statistics, computing, and data analysis. It occurs in phrases such as tölulegar aðferðir (numerical methods), töluleg gögn (numerical data), töluleg forrit (numerical programs), and tölulegt gildti (numerical value). It can also appear in contexts contrasting numerical with qualitative attributes, e.g., gögn sem eru töluleg vs. eigindleg gögn (qualitative data).

Related terms include tölfræði (statistics), which covers the science of analyzing numerical data, and tölfræðilegur, meaning statistical. The distinction between tölulegur and tölfræðilegur is often subtle: tölulegur emphasizes numbers themselves, while tölfræðilegur relates to statistical analysis or methods.
