Nulovým

Nulovým is a Czech word-form used as the instrumental singular of the adjective nulový, which means zero or null. The base adjective narrows to masculine or neuter in the instrumental form as nulovým, while feminine instrumental singular takes the form nulovou. In practical terms, the instrumentally used phrases include s nulovým bodem, nulovým rozsahem, or nulovou hodnotou, illustrating how the zero or null meaning attaches to different nouns in various genders.

In everyday language and in technical contexts, nulový describes something that is zero, nonexistent, or without effect. It is common in mathematics, physics, statistics, and engineering to express zero magnitude, zero value, or absence of a quantity. For example, nulová hodnota refers to a zero value, while nulový signál can denote a signal of zero strength. The term is also widely used in phrases for describing lack of effect or impact, such as nulový účinek.

Etymologically, nulový derives from nula, the Czech word for zero, and has been part of Czech technical and scientific vocabulary for centuries. As a standard adjective, its forms follow ordinary Czech declension rules, allowing it to agree with gender, number, and case of the noun it modifies.

Common related terms include nulová hypotéza (null hypothesis), nulová konstanta (zero constant), and nulový bod (zero point). The instrumental form nulovým appears in constructions after prepositions like s or při, and with masculine or neuter nouns, while feminine nouns use nulovou.
