Neádoucím

Nežádoucím is the instrumental singular masculine form of the Czech adjective nežádoucí, meaning undesirable or unwanted. The form neádoucím is not standard Czech and is generally considered a misspelling or typographical error; the correct instrumental form is nežádoucím. The base adjective nežádoucí is used to describe something that is not desired in a given context.

Usage in Czech is common in formal, administrative, and scientific language to label effects, behaviors, or phenomena that are not desired. Typical collocations include nežádoucí účinky (undesirable side effects), nežádoucí jev (undesirable phenomenon), and nežádoucí dopady (undesirable consequences). The word is regularly used in medical literature, regulatory texts, safety assessments, and policy discussions to flag issues that should be avoided or mitigated.

Etymology and morphology: nežádoucí is formed by the negating prefix ne- attached to the root žádo- from žádat or žádost, relating to desire or being desired, with the suffix that yields the meaning desirable. The prefix ne- reverses this meaning to indicate the opposite. As with other Czech adjectives, nežádoucí declines to match the noun it accompanies; the instrumental masculine singular form is nežádoucím, and the form adapts for other genders and cases accordingly.
