Tattarrattat is an English word which means ‘a knock at the door’; the sound one hears when someone knocks on the door, especially when the sound is rhythmic.
The 12 letter word has its etymology from Ulysses, a 1922 Novel by James Joyce. Tattarrattat is one of the longest palindromic words in the English language. It’s also one of the longest onomatopeias.
Tattarrattat looks and sounds like a tongue-twister, right? When I tried repeating it as fast as I could, my tongue got twirled by the fourth repetition. You can beat me! Have fun😀
