Reálne
Reálne is a word used in Slovak and Czech with several related senses. As an adjective and adverb, it means real, actual, genuine, or feasible, describing something that exists in reality or corresponds to facts rather than to theory or appearance. In everyday language it is used to emphasize practicality or authenticity: for example, "reálne problémy" (real problems), "reálna situácia" (the real situation), or "reálna cena" (the current price). The term can also replace "skutočný" in many contexts, though nuances may differ by dialect.
In mathematics, Slovak and Czech speakers use "reálne čísla" or "reálné čísla" to denote the real numbers.
Outside mathematics, the sense of reálne as "real" or "actual" remains central to distinguishing fact from hypothesis,
