invalidní

Invalidní is a Czech adjective derived from invalidita, meaning disability or impairment. It is used primarily in medical and legal contexts to describe conditions, statuses, or objects related to disability. Common compound terms include invalidní důchod (disability pension), invalidní vozík (wheelchair), and invalidita (disability as a formal status). The word should not be confused with neplatný, which means not valid in the sense of an invalid contract or document.

In the Czech Republic, disability status is classified into three degrees: I. stupeň invalidity, II. stupeň invalidity, and III. stupeň invalidity. This classification influences eligibility for benefits, social support, and certain rights. The term invalidní důchod refers to pension benefits granted on the basis of disability, administered by the Czech Social Security Administration (ČSSZ) or related institutions. Assessments of invalidity are typically conducted by medical committees and social authorities.

Usage notes: invalidní describes the disability-related nature of a condition or item, while adjectives like postižený or the phrase osoba se zdravotním postižením are used to refer to a person with a disability in contemporary Czech language. The term invalidní is distinct from neplatný (not valid) and is not generally used to denote the invalidity of documents; in those cases, neplatný or neplatnost would be used.
