There are slightly less than 171,5 thousand words in English language according to the newest Oxford English dictionary. The length of words varies.

Our List of 10 Longest English Words

10. Incomprehensibilities

Perhaps you already know this term. As an aperitif to more complicated ones, this word is even pronounceable, so if you are interested, watch thematic Youtube videos or use Google voice services. This rather impressive 21-letter word is not hard to understand, as it means something impossible to comprehend. Ask your friends about their incomprehensibilities and have fun. If they find it hard to translate, guide them through the top translation companies that always get it right. A not long time ago, in the 90s, the incomprehensible word set the record as the longest one. However, it won only in the category of the longest words “in common usage.”

9. Dichlorodifluoromethane

The longest word in English language refers to sciences such as chemistry or medicine because these spheres of knowledge operate complicated nouns that are coined from several words to describe one phenomenon. Dichlorodifluoromethane, a 23-letter-long term, is one of such words, as it is a chemistry term which means a chlorofluoromethane CF2Cl2. This is a colorless gas that is widely known under the name Freon-12, which you may have heard before. This gas is a refrigerant and aerosol spray propellant that is used for medical purposes.

8. Honorificabilitudinitatibus

Interestingly, this 27-letter word came to us from English literature. We owe Shakespeare not only world-known plays and sonnets but also this splendid word. This word is Latin and means the state when the person can achieve honors. It is mentioned in Scene I of Love’s Labour’s Lost by a character Costard. This word also set a record as one of the long English words which feature only alternating consonants and vowels. However, it may be that Shakespeare borrowed this word from medieval manuscripts because it was widely used by scholars and grammarians circa. 1055.

7. Antidisestablishmentarianism

This word is only one letter more than the previous one on the list. However, its meaning differs greatly and signifies a political movement of past centuries. It originated in 19th century Britain which wanted to separate state and church. At the time, the term meant a certain political movement that aimed to disestablish the Church of England as the official state church of Wales, Ireland, and England. So, people who belonged to this movement, thought that the Church is an integral part of the state which needs patronage and protection from the government. This is one of the longest English words of non-scientific origin, although it is absent from some dictionaries.

6. Floccinaucinihilipilification

With its impressive 29 letters, this word is the longest non-technical word in the English language. Although not all dictionaries recognize it, the word flourishes. It signifies the habit when the person describes or treats something as not important, worthless, or without value. Notably, it contains a bunch of Latin words that mean “nothing,” so perhaps, it is used mostly in humorous ways. The first usages are dated back to 1741, but it is also used nowadays. For example, it was used in Parliament on 21st February 2012 by a Conservative Jacob Rees-Mogg.

5. Supercalifragilisticexpialidocious

Originally, this is the name of a song from the musical Mary Poppins released by Disney in 1964. By this word, Mary Poppins tried to describe her feelings after she won a horse race. If we decode this word and analyze its components, it will mean something like “atoning for educability through delicate beauty,” as one of the academics said. Or, in other words, it is about everything great, glorious, grand, superb, wonderful, and splendid. Later, people even used this term for other songs.

4. Hippopotomonstrosesquippedaliophobia

If you are reading this article, then perhaps, you don’t have hippopotomonstrosesquippedaliophobia. You will never guess, but this word means the fear of long words! The 36-letter word is not recognized by the American Psychiatric Association. However, it falls into a definition of social phobia. When the person sees long words, they feel fear and anxiety which sometimes leads to panic. A person with this phobia can experience sweating, dizziness, trembling, headache, trouble breathing, and even avoiding reading because of the fear.

3. Bababadalgharaghtakamminapronnkonnbronntonnepronntuonnthunntrovarrhounawnskawntoohoohoordeenenthurnuk

If this is only #3, then what is the longest word in the world?! This 101-letter term was coined by James Joyce, an author best known for his Ulysses. The Irish author used the term in the novel Finnegan’s Wake. In fact, the word aims to represent the sound of thunderclap which happened after Eve and Adam fell from Heaven. James Joyce is known for his many literary experiments such as the “stream of consciousness” a technique in which he directly “translated” subconscious thoughts of heroes into the text of the novel. It’s no wonder that he created such a breathtaking word which indeed sounds like a long sound which goes after a strike of a thunderbolt.

This is the longest word in the English language with its impressive 189,819 symbols. Like many long words, this one comes from chemistry and signifies a protein structure.

This technical name is never pronounced and is rather used to give a full scientific name for a substance. This protein is commonly known as titin, or methionyl...isoleucin, but if you try to pronounce its full name, it may take you three and a half hours to spell it.
