Longest English Words

 Have you ever had trouble finding a word to express yourself? Or maybe you just love long words. Whatever the reason, there are some amazing words in English that are both impressive and often useful. From medical terms to honorifics, here's a list of the 20 longest words in English.

Supercalifragilisticexpialidocious

This fun and impressive 34-letter word was first mentioned in the 1964 Disney movie “Mary Poppins.” It means extremely good, marvelous, or delightful and can be used to express surprise or joy. Although it has no scientific significance, it surely is the second longest English word.

Floccinaucinihilipilification

Floccinaucinihilipilification is an incredibly long word, which can be broken down into four meaningful parts: "flocci," "nauci," "nihili," and "pilification". “Flocci” means “a small tuft of feathers or wool,” “nauci” translates to one-fourth of an ounce, “nihili" is the Latin for “nothing," and the verb “pilify" means to treat something as worthless. Together, this combination creates the meaning of deeming something as valueless or insignificant.

Pseudopseudohypoparathyroidism

Pseudopseudohypoparathyroidism is a medical condition first reported in 1952. It is characterized by the bone deformities and enlarged wrists that are typical of Albright’s hereditary osteodystrophy, as well as mild resistance to the actions of parathyroid hormone. The name comes from Greek words meaning “false, false, hypo- + parathyroid.” Patients with this disorder have only a mild resistance to the hormone and may require calcium supplementation if they do not consume enough in their diet.

Antidisestablishmentarianism

Antidisestablishmentarianism is a term coined in the 19th century during debates over Church of England disestablishment in Ireland, Scotland, and Wales. This word isn’t used as often today, except perhaps as a tongue twister among those who are fascinated by long words! That is to say, opposed to a state ceasing to fund or recognize a recognized religion.

Unimaginatively

Unimaginatively is one of the longest words in English that has only one syllable and is used to describe someone or something with a lack of imagination, creativity, or inventiveness. It consists of 12 letters which makes it an ideal word choice when you're looking for an impressive, lengthy word!
