upozorujú

Upozorňují is the present tense, third person plural form of the Czech imperfective verb upozorňovat, meaning they warn, alert, or draw attention to something. The action is transitive and commonly takes a complement introduced by na, to indicate what is being warned about (for example, na nebezpečí or na problém). In non-diacritic texts you may occasionally see a variant without the háček, but the standard spelling in Czech is upozorňují.

Grammar and usage: Upozorňují is used in formal and informal contexts to notify people about risks, changes, or important information. It often appears in public announcements, news reporting, safety advisories, and health warnings. The related perfective form upozornit expresses a single warning with a future effect, while the imperfective upozorňovat describes the act of warning in general or repeatedly.

Examples:

- Upozorňují na riziko zranění. (They warn about the risk of injury.)

- Lékaři upozorňují na vedlejší účinky léků. (Doctors warn about potential side effects of the medications.)

- Internetová platforma upozorňuje uživatele na podvodné zprávy. (The online platform alerts users to scam messages.)

Notes: Upozorňují can also mean “they point out” or “they remind” in contexts where attention is drawn to specific information. Its antonyms include varovat (to warn) and upozornit (to warn, often with a sense of issuing a one-time notice). The verb is used across media, education, and official communications to convey caution or necessary information.
