rychlého

Rychlého is a declined form used in Czech grammar. It is the genitive singular of the masculine adjective rychlý, which means fast or quick, and it is also the genitive singular form of the surname Rychlý. In Czech, both adjectives and surnames decline by case, number, and gender, so rychlý becomes rychlého in the masculine genitive.

As a surname, Rychlý refers to a family name derived from the same adjective. In sentences, Rychlého typically appears in the genitive where a noun or pronoun governs possession or relation. For example, in the phrase Dům pana Rychlého, meaning “the house of Mr. Rychlý,” the surname is inflected to Rychlého to show possession. The form also occurs with other nouns in genitive constructions, such as Kniha rychlého koně in context, though more common examples involve personal names.

Usage notes and context: rychlého can be encountered in literary, journalistic, and formal texts where a male or masculine-named subject is referred to in possession or association. The feminine form of the surname would decline differently (e.g., rychlá for nominative, rychlé for certain genitives, depending on the base name). The word itself remains rooted in the Czech adjective rychlý, highlighting the link between a descriptive descriptor and a hereditary surname.
