Aritmetickou

Aritmetickou is the instrumental singular feminine form of the Czech adjective aritmetický, meaning arithmetic. It is used to modify feminine nouns in the instrumental case and does not denote a standalone concept by itself. In Czech, adjectives agree with the nouns they describe in gender, number and case, and aritmetickou appears whenever the noun is feminine and in instrumental.

In practice, aritmetickou commonly appears in mathematical or educational phrases. For example, s aritmetickou operací means with an arithmetic operation, and aritmetickou metodou describes doing something by an arithmetic method. These constructions illustrate how the form accompanies the noun in instrumental phrases, indicating the manner or means by which something is done.

Etymology and relation to arithmetic: the adjective aritmetický derives from aritmetika, the field of arithmetic, itself rooted in Greek and Latin scholarly terms. Aritmetickou serves as the feminine instrumental inflection of that adjective, enabling precise grammatical expression in sentences that involve operations, methods or other feminine nouns in instrumentality. It is thus a grammatical form rather than a separate topic, used across mathematical and linguistic contexts to describe arithmetic-related attributes or actions.
