Longest Words - English

English

The longest technical word in English is the scientific name for the protein titin, at 189,819 letters. Titin is the largest known polypeptide in the human body, composed of 34,350 amino acids. Though lexicographers regard generic names of chemical compounds as verbal formulae rather than English words, for its sheer length it is often included in longest-word lists.

The 45-letter word pneumonoultramicroscopicsilicovolcanoconiosis is the longest English word that appears in a major dictionary. Originally coined to become a candidate for the longest word in English, the term eventually developed some independent use in medicine. It is referred to as "P45" by researchers.

Antidisestablishmentarianism, at 28 letters, is the longest non-coined, non-technical English word. It refers to a 19th century political movement that opposed the disestablishment of the Church of England as the state church of England.

Floccinaucinihilipilification, at 29 letters (and meaning the act of estimating something as being worth so little as to be practically valueless, or the habit of doing so), is the longest non-technical, coined word in the English language.

Famous quotes containing the word english:

    “Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
    —John Michael Hayes (b.1919)

    “The traveler to the United States will do well ... to prepare himself for the class-consciousness of the natives. This differs from the already familiar English version in being more extreme and based more firmly on the conviction that the class to which the speaker belongs is inherently superior to all others.”
    —John Kenneth Galbraith (b. 1908)

    “If English is spoken in heaven ... God undoubtedly employs Cranmer as his speechwriter. The angels of the lesser ministries probably use the language of the New English Bible and the Alternative Service Book for internal memos.”
    —Charles, Prince Of Wales (b. 1948)
