World’s longest word takes 3.5 hours to pronounce


ESQUIRE, RUSSIA (CW39) – If someone says they’d like to have a word with you, make sure it’s not this one! It’s the longest word in English and if you want to read it, here’s a look. A word of warning… the “word” takes about 3.5 hours to say.

The word is 189,819 letters long. It’s actually the name of a giant protein called Titin. Proteins are usually named by mashing-up the names of the chemicals making them. And since Titin is the largest protein ever discovered, its name had to be equally as large.
