úspným

úspným is not a standard word in Slovak or Czech; it appears to be a misspelling or truncated form of the instrumental singular úspešný in Slovak or úspěšný in Czech. The forms share a common root in the noun úspech/úspěch meaning "success." The correct instrumental singular form is úspešným (Slovak) or úspěšným (Czech), with diacritics indicating pronunciation.

In Slovak, úspešný is an adjective meaning "successful" and is declined to agree with the noun it modifies. The instrumental singular form úspešným is used in constructions such as "bol úspešným človekom," meaning "he was a successful man." In Czech, the analogous form is úspěšným, as in "byl úspěšným učitelem," meaning "he was a successful teacher." These forms reflect standard adjective agreement and case usage in their respective languages.

If úspným appears in a text, it is likely a typographical error, a dialectal variant, or a truncation of one of the standard forms. Editors and readers should verify the language context and consult a dictionary to determine whether the intended word is úspešný/úspěšný or another related term. When in doubt, examining surrounding words and grammar can clarify the intended meaning.
