The Longest Word in the World
The longest word ever recorded comes from chemistry. It is the name of a protein:
Methionylthreonylthreonylglutaminylarginyl...isoleucine (189,819 letters)
This word is so long that it would take hours to say! It is the full chemical name of titin, the largest known protein. However, scientists usually just call it "titin" because the full name is impractical.
The Longest Words in Other Languages
Many languages also have extremely long words, often in legal, medical, or scientific fields.
