The Spanish language is one of the most widely spoken in the world, so it’s no surprise that there are some pretty long words in Spanish! Spanish may seem simple because you have many cognates with English, but it has some hidden complexities when it comes to its pronunciation and even its grammar. And when it comes to the longest word in Spanish, things get fascinating…

About the Spanish Language

The Spanish language is a Romance language that originated in the Iberian Peninsula. It is the second most natively spoken language in the world, with over 460 million speakers. The longest word in Spanish, according to the major dictionaries, is Esternocleidooccipitomastoideos, a 31 letter word for a muscle in the human neck.

While agglutinative languages like Maori and Turkish can create even longer words, these are not found in everyday language usage.

For Spanish speakers, knowing the longest word can be a fun way to impress others with their knowledge of the language. Yet, for those who study medical terms or specific English terms, this word may not come up often enough to memorize it without consulting a dictionary.

And the same goes for any other technical term you might need to know. In fact, many times, people will use what they know as slang instead of spelling out a technical term when speaking casually.
