Prasknout

Prasknout is a Czech verb meaning to burst, to pop, or to crack, describing a sudden rupture of something under pressure, such as a balloon, a tire, or a pipe, as well as more general ruptures of materials. It can also be used metaphorically, for example to burst into laughter (prasknout smíchy).

Etymology and form: The verb derives from the onomatopoeic root prask-, mirroring the sharp sound of bursting. It is usually used in its perfective aspect; the imperfective counterpart is praskat (and, in some contexts, praskávat) when describing ongoing or repeated ruptures. The past tense forms are praskl (masc), praskla (fem), and prasklo (neut). The noun prasknutí denotes the act or result of bursting.

Usage notes and examples: Literal uses include Balón praskl. Hadice praskla. Předčasné zatížení vedlo k prasknutí hadice. Figuratively, prasknout smíchy is a common expression meaning to break into loud laughter: Diváci praskli smíchy. The phrasing is characteristic of everyday Czech and appears in both spoken and written language.
