Dodatnia

Dodatnia is the feminine singular form of the Polish adjective dodatni, meaning positive, favorable, or constructive. It agrees with feminine nouns in gender and number and is used in various contexts to denote positivity or beneficence. Common uses include phrases such as dodatnia odpowiedź (positive answer), dodatna ocena (favorable grade), or dodatnia diagnoza (positive diagnosis).

In mathematics and science, dodatnia liczba refers to a positive number—one greater than zero. The plural form is liczby dodatnie. The concept is opposed by liczbа ujemna (negative number) and by zero, which is neutral in this sense. The masculine and neuter forms accompany corresponding nouns, e.g., dodatni wynik (positive result) and dodatnie badanie (positive test).

In medical and everyday usage, the feminine form is common when describing feminine nouns: dodatnia odpowiedź or dodatnia diagnoza indicates a positive result or finding. In general, dodatnia carries the same semantic field as the more international pozytywny but may imply a factual, verified positivity rather than subjective approval.

Etymology: the word derives from Latin positivus via Polish adoption; two common Polish synonyms exist: dodatni and pozytywny.
