Yes, you read that right. The longest word in English is not antidisestablishmentarianism, pneumonoultramicroscopicsilicovolcanoconiosis, or even supercalifragilisticexpialidocious. It is a word that has a whopping 189,819 letters and takes about three and a half hours to pronounce.

What is this word, you ask? Well, it is the full name of the protein titin, which is also known as connectin. Titin is the largest protein in the human body and is responsible for the elasticity and contraction of muscles. It is composed of 244 individually folded protein domains connected by unstructured peptide sequences.

The full name of titin is derived from the names of these domains and peptide sequences, which are mostly Greek letters and numbers. The word starts with methionyl… and ends with …isoleucine. It has 189,819 letters and 63,206 syllables.

If you are curious to see or hear the full word, you can check out this video at https://www.youtube.com/watch?v=Hz6NezJyqgo, or visit https://www.digitalspy.com/fun/a444700/longest-word-has-189819-letters-takes-three-hours-to-pronounce where you can see the word written out.

Hello Lew - thank you for letting us know.  Although the news of learning this information may last longer than a moment, there's no way I will recall much knowledge of it later today.
