kladná

Kladná is the feminine singular form of the Czech adjective kladný, meaning positive, favorable, or affirmative. It is used to describe feminine nouns and agrees with the noun in gender and number. Examples include kladná odpověď (a positive/affirmative answer), kladná hodnota (a positive value), and kladná stránka věci (the positive side of a matter). The masculine form is kladný and the neuter or plural forms are kladné or kladná, depending on the noun.

In mathematics and science, kladná is used in phrases such as kladná čísla (positive numbers) and kladná hodnota (positive value). In physics or electronics, kladná polarita refers to the positive polarity. The corresponding opposite term is záporná (negative).

Etymology traces kladná to the root kladný, itself linked to a common Slavic concept of being favorable or good. The term appears across contexts—linguistic, educational, and technical—where positivity, approval, or favorable quality is being described.

See also: kladný, záporný. Note that kladná is specifically the feminine form; other gendered forms (kladný, kladné) are used to match masculine or neuter nouns. The word is common in everyday Czech as well as in scientific and formal writing to indicate positivity or agreement.
