prawdopodobna

Prawdopodobna is the feminine singular form of the Polish adjective prawdopodobny, meaning "probable" or "likely." It is used to describe a noun with feminine grammatical gender and agrees with number and case according to standard Polish adjectival declension. The neutral and masculine counterparts are prawdopodobne and prawdopodobny, respectively; plural forms include prawdopodobne (non-personal) and prawdopodobni (personal).

In everyday language prawdopodobna qualifies events, causes, explanations or outcomes perceived as having a higher likelihood than not, for example: "To jest prawdopodobna przyczyna" ("This is a probable cause"). In formal contexts, especially in statistics and probability theory, the related noun prawdopodobieństwo denotes the quantitative measure of likelihood, while the adverb prawdopodobnie corresponds to "probably" or "likely."

Comparative and superlative forms are formed analytically in contemporary Polish (bardziej prawdopodobna — "more probable"; najbardziej prawdopodobna — "most probable"). Common antonyms include mało prawdopodobna ("unlikely") and niemożliwa ("impossible").

Prawdopodobna appears across registers from colloquial speech to scientific writing and is a basic term in discussions about uncertainty, hypothesis evaluation and risk assessment.
