Top 10 Longest Words in English Language


On this article, we listed the top 10 longest words in English language. But unfortunately, we couldn't include the longest word we found because it will be "inefficient" to add the chemical name of Titin/connectin. The chemical name of Titin is an 189,819 letter word which will take about fifty-seven pages to write. But if you are too curious about the longest English word, you can totally listen to the pronunciation of this word on a Youtube video titled "The Longest Word in English (Pronounced)". And one more thing, you need just 3 and a half hours to finish listening to the pronunciation.

From my personal experience, I can tell you that it was not very pleasant to listen to the pronunciation of this "way too long" word. So, you may just move on and enjoy this article. Here we listed the officially recognized longest words in English. Let's take a look at these long words.

Top 10 Longest Words in English

1. Pneumonoultramicroscopicsilicovolcanoconiosis (45 letters)


This is by far without any doubt, the longest word in any major English dictionary. It's actually a medical term for a disease just like pneumoconiosis caused by inhalation of very fine silicate or quartz dust. This is the longest word in English according to many reknowned linguistics experts.

2. Hippopotomonstrosesquipedaliophobia (35 letters)


This is a considerably long word that literally means the fear of long words. Only some people with nice humor can understand the irony on this word. There is a long word song about this word. It is unlikely that this 15-syllable contrivance is ever used purely for its meaning. This word is just for fun and instead, the term sesquipedalophobia is recognized in formal writing.

3. Supercalifragilisticexpialidocious (34 letters)


This long word is also coined by writers Sherman Brothers for a song from the 1964 Disney musical film Mary Poppins. You can watch the video song containing this very long word. The Oxford English Dictionary estimates that the word "Supercalifragilisticexpialidocious" was first attested in the 1940s. The roots of the word have been defined as follows: super- "above", cali- "beauty", fragilistic- "delicate", expiali- "to atone", and -docious "educable", with the sum of these parts signifying roughly "Atoning for educability through delicate beauty." According to the film, in which the word gained its popularity, it is defined as "something to say when you have nothing to say". However, it is commonly defined as "extraordinarily good" or "wonderful" as all references to the word in the film can be perceived as positive. Dictionary.com also notes that the word is "used as a nonsense word by children to express approval or to represent the longest word in English." - (wikipedia)

4. Pseudopseudohypoparathyroidism (30 letters)


Pseudopseudohypoparathyroidism (pseudoPHP) is an inherited disorder, named for its similarity to pseudohypoparathyroidism in presentation. The term pseudopseudohypoparathyroidism is used to describe a condition where the individual has the phenotypic appearance of pseudohypoparathyroidism type 1a, but is biochemically normal. The name of this disorder is a very long word.

5. Floccinaucinihilipilification (29 letters)


The word has many parts consiting of many latin words like flocci, from floccus (a wisp), nauci, from naucum (a trifle), nihili, from nihil (nothing), pili, from pilus (a hair). So all of these have the sense of "pettiness" or "nothing". This is the estimation of something as valueless. Ironically, "floccinaucinihilipilification" is a valueless word itself because it’s almost never used anywhere.

6. Antidisestablishmentarianism (28 letters)


The English word antidisestablishmentarianism is notable for its unusual length of 28 letters and 12 syllables, and is one of the longest words in the English language. It has been cited as the longest word in the English language, excluding coined and technical terms. Antidisestablishmentarianism was a political position during the Reformation. King Henry VIII wanted to divorce his wife, so he split from Roman Catholicism. Those against him were "anti" the "disestablishment" of the church and thus, didn't approve of the budding Anglican Church, later known as the Church of England.

7. Honorificabilitudinitatibus (27 letters)


Honorificabilitudinitatibus is the dative and ablative plural of the medieval Latin word honorificabilitudinitas, which can be translated as "the state of being able to achieve honours". It is mentioned by the character Costard in Act V, Scene I of William Shakespeare's Love's Labour's Lost. As it appears only once in Shakespeare's works, it is a hapax legomenon in the Shakespeare canon. It is also the longest word in the English language featuring only alternating consonants and vowels.

8. Incomprehensibilities (21 letters)


Incomprehensibility means something that is difficult or impossible to understand or comprehend. This word set the record in the 1990s as the longest word “in common usage.” It also means Archaic. limitless; not limited or capable of being limited. And it is one of the longest words you can use.

9. Antisesquipedalianist (21 letters)


This word is originated from the root word, sesquipedalian; which means "given to long words". This is similer to the other long word "Hippopotomons-trosesquipedaliophobia" that you have seen earlier on this list. Sesquipedalian could describe a speech or some form of written communication and has negative connotations, i.e., the piece is difficult to understand because of the contrived use of long words for which shorter words could have been used, possibly designed by the speaker/writer to sound smarter or more educated than they are. The prefix anti- can indicate to the opposite meaning of the word and the suffix -ist assume that it would mean "one who is prone to the contrived over-usage of long words". Therefore, an antisesquipedalianist is either one who uses small words or one who is opposed to the contrived over-usage of long words. (Answers.com)

10. Lopadotemachoselachogaleokranioleipsanodrimhypotrimmatosilphioparaomelitokatakechymenokichlepikossyphophattoperisteralektryonoptekephalliokigklopeleiolagoiosiraiobaphetraganopterygon (182 letters)


Believe it or not; the above one is not just some random letters pressed on a keyboard by a 6 months old kid. This is the name of a fictional dish mentioned in Aristophanes' comedy Assemblywomen. Though it could be the longest word in the history of English, it is not yet officially recognized as the longest word and not included in any dictionary. But we can totally consider this word as it is the longest word ever to appear in literature and coined by a major author.
