What's the biggest word in the world?

Do you know what the biggest word in the world brings together all languages? Some must imagine that it comes from the German language, due to the reputation of putting words together to form a single word. Really? German is not the only language that does this.

The biggest word in the world comes from the Greenlandic language of Denmark and has an incredible 156 letters:

  • nalunaarasuartaateeraaranngualioqatigiiffissualioriataallaqqissupilorujussuanngortartuinnakasinngortinniamisaalinnguatsiaraluallaqqooqigaminngamiaasiinngooq

This giant word means something like: “there have been reports that apparently - God knows how many times - once again considered whatever I, despite my poor condition, could still be considered quite competent and ingenious as an initiator to put a consortium in for the establishment of a range of small radio stations ”. 

Unfortunately, this unpronounceable word is not the largest in the world. But how so? Well, there are words for bigger technical terms that are. There are actually words over 100,000 letters long and it takes hours to be pronounced.

This is the chemical name of titin, the largest known protein, with its incredible 189,819 letters that I will certainly not put in this article because it would occupy a very heavy weight on this page. It starts and ends like this:

  • Methionylthreonylthreonylglutaminylalanyl ………… ..isoleucine

There is a video of more than 3 hours of a human reading this word that must be bigger than a book, see below:

Amazingly, that word is in the Portuguese and English language.

The longest and most used word in everyday life comes from the Dutch language and has 38 letters. This word is so common that it is often abbreviated as MPS. Look:

  • Meervoudigepersoonlijkheidsstoornissen

Its meaning is something like "Various personality disorders".
