Realne

Realne is the ASCII rendering of the Czech/Slovak adjective reálné, meaning real, genuine, or realistic. In Czech and Slovak, reálné is used to describe things that exist in reality or are practical, as opposed to imaginary or theoretical. The non-diacritic form realne appears in plain-text contexts, such as programming identifiers or older texts where diacritics are omitted.

In mathematics, the related phrase reálné číslo denotes a real number; realné numbers are elements of the real number system and contrast with complex or imaginary numbers. The adverb reálně means realistically or practically; for example, “to je reálně možné” means “that is realistically possible.” The forms of the adjective adjust for gender, number, and case in Czech and Slovak, but the underlying meaning remains tied to reality, actuality, or practicality.

Because realne is not a standard English word, it is not used in English-language mathematical or linguistic literature except when quoting the Czech/Slovak term or when it appears as a brand or product name. In English texts, it is typically understood only as the ASCII form of the diacritic-bearing word rather than as a distinct English term.
