Rýchlos

Rýchlos is not a standard word in contemporary Slovak usage. In most contexts, the concept of speed is expressed by the noun rýchlosť, which denotes the rate or manner of movement or change. The form rýchlos does not appear as an independent entry in major Slovak dictionaries and is not used as a common lexical item.

Linguistic note: rýchlosť is formed from the adjective rýchly (fast) with the nominalizing suffix -osť, yielding an abstract noun that signifies the property of being fast. The stem rýchlo- or rýchlos- functions within this word rather than as a standalone word in modern Slovak. As a result, rýchlos is typically not treated as a separate lexeme in standard grammar and dictionaries; when it is encountered, it is usually as a historical, dialectal, or typographical anomaly rather than as a recognized independent term.

Usage and occurrence: In current Slovak, rýchlos is generally considered incorrect or nonstandard when used to mean speed. It may appear only as part of older texts, regional speech, or as a mistaken truncation in informal writing. For precise communication, the correct form to express the abstract quality of speed is rýchlosť, as in contexts ranging from physics to everyday description of motion.
