numerical

The word 'numerical' is built upon the Latin root numerus, meaning "number" or "quantity," which itself may trace back to the Proto-Indo-European root nem-, meaning "to assign, allot, or take." The suffix '-ical' is a productive adjectival ending in English, derived from Latin via French, used to form adjectives meaning "pertaining to." Thus, the literal construction is "pertaining to number." This etymological logic is transparent: the core concept of number, inherited from classical Latin, is directly extended into the modern abstract sense of anything expressed by, involving, or relating to numbers, distinguishing it from qualitative descriptions.
