potlesk

Potlesk is a Czech noun meaning applause, the act of clapping hands to express approval or appreciation, typically at the end of a performance, speech, or public presentation. It is a common social gesture in theatres, concert halls, and public ceremonies in Czech-speaking regions, and may be accompanied by a bow or curtsey from the performers.

The word derives from the Czech verb tleskat, to clap, with potlesk as the noun form. It is standard in Czech and Slovak language contexts; in international or multilingual settings, the concept is often described as applause or may be referred to by the loanword aplaus or similar terms in some contexts.

Forms and etiquette of potlesk vary by context. A standard round of applause may be brief and subdued, while a long or vigorous clapping can become a standing ovation, known in Czech as potlesk na stojáka, used to show strong appreciation. The timing of applause—whether after each act or at the end of the program—often follows cues from the performer, conductor, or host, and can be influenced by cultural norms and the nature of the event.

Cultural role and function: Potlesk serves as a nonverbal feedback mechanism signaling approval and encouragement for performers, speakers, or presenters. It can help acknowledge skill or effort, influence the pacing of an event, and sometimes prompt encores or extended bows.
