dvojitou

Dvojitou is the feminine singular form of the Czech adjective dvojitý, meaning "double" or "dual." It is used to describe a feminine noun in certain grammatical cases, most commonly the accusative and instrumental.

In Czech, adjectives agree with the nouns they modify in gender, number, and case. Dvojitou appears when the noun is feminine and in the accusative singular or instrumental singular. The base form dvojitý has other endings for masculine, neuter, and other cases (for example, dvojitá in nominative feminine, dvojité in neuter).

Etymology traces dvojitou to the root dvoj- meaning "two," combined with the adjectival suffix -itý, forming the meaning "double." The word is used in everyday language to emphasize duplication or duality in relation to a feminine noun.

Usage examples include phrases such as "dvojitou dávkou" (with a double dose), "dvojitou šancí" (with a double chance), and "dvojitou cestou" (by a double route). In each case, the form remains dvojitou to agree with the feminine noun and to indicate the sense of duplication or excess.

Dvojitou thus functions primarily as a grammatical form within Czech, conveying the sense of "double" when paired with feminine nouns in appropriate cases. It illustrates how Czech adjectives morph to reflect case and gender in a richly inflected language.
