Meaning
Expressing doubt about a fact.
Cultural Background
In Polish academic culture, using 'nie mam pewności' is a sign of intellectual rigor. It shows you aren't making claims without evidence. Poles value directness, but 'nie mam pewności' is a standard 'safe' phrase in negotiations to avoid over-promising. In regional dialects, you might hear variations, but 'nie mam pewności' remains the standard bridge for communication with non-dialect speakers. Young Poles often shorten this to 'Nie jestem pewien/pewna' in texts, but 'nie mam pewności' is still used for emphasis.
The 'Czy' Rule
