Strč prst skrz krk
Strč prst skrz krk is a Czech and Slovak tongue-twister meaning "stick a finger through the throat".
The sentence is well known for being a semantically and syntactically valid clause without a single vowel, the nucleus of each syllable being a syllabic r, a common feature among many Slavic languages. It is often used as an example of such a phrase when learning Czech or Slovak as a foreign language.
In fact, both Czech and Slovak have two syllabic liquid consonants, the other being syllabic l. As a result, there are plenty of words without vowels. Examples of long words of this type are ', ', and čtvrtsmršť, the latter two being artificial occasionalisms.
There are other examples of vowelless sentences in Czech and Slovak, such as prd krt skrz drn, zprv zhlt hrst zrn, meaning "a mole farted through grass, having swallowed a handful of grains".
