nezdravého

Nezdravého is a form of the Czech adjective nezdravý, which means unhealthy or not in good health. The prefix ne- negates zdravý, so nezdravý describes something lacking health or contributing to poor health. Nezdravého is the genitive singular masculine (and can also appear in neuter) form of nezdravý and is used before masculine or neuter nouns in contexts requiring the genitive case, or after prepositions that govern genitive.

In Czech, adjectives decline to agree with the noun they modify. The feminine forms differ (nezdravá, nezdravé), and the plural forms are nezdraví (masculine personal), nezdravé (neuter and feminine plural in certain cases). The form nezdravého specifically appears in phrases such as nezdravého člověka (of an unhealthy person) or vliv nezdravého životního stylu (the influence of an unhealthy lifestyle).

Usage and context: nezdravého is common in medical, health, and nutrition discourse, as well as in everyday language when describing health status, risks, or conditions. It is often contrasted with zdravý or zdravější to discuss healthy behavior, foods, environments, or habits. For example, Nezdravého člověka často postihují opakované respirační potíže, or Vliv nezdravého životního stylu se projevuje na délce života.

Etymology: nezdravý is built from zdravý (healthy) with the negating prefix ne-; both derive from the Czechic root related to health and well-being. The prefix ne- is productive in forming antonyms across many Czech adjectives.
