2364: Czech's Vowelless Tongue-Twister Jun 8, 2021
The Czech language has a nasty tongue-twister without any vowels:
Strč prst skrz krk
This is notably as well because it is totally grammatically sound, meaning 'stick your finger through your throat': quite fitting too. Indeed, those words are all fairly normal, and are among many without vowels. The way this is possible from a syllabic point is that each word has [r] which is acting as a so-called syllabic-R. English also has syllabic consonants such as the [m] in 'column' wherein a consonant is a whole syllable. This is very common in Slavic languages too, especially around [r], [l] and sometimes [m] hence the word čtvrtsmršť (a type of measurement).
