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:

    The English masses are lovable: they are kind, decent, tolerant, practical and not stupid. The tragedy is that there are too many of them, and that they are aimless, having outgrown the servile functions for which they were encouraged to multiply. One day these huge crowds will have to seize power because there will be nothing else for them to do, and yet they neither demand power nor are ready to make use of it; they will learn only to be bored in a new way.
    Cyril Connolly (1903–1974)

    Where dwells the religion? Tell me first where dwells electricity, or motion, or thought or gesture. They do not dwell or stay at all. Electricity cannot be made fast, mortared up and ended, like London Monument, or the Tower, so that you shall know where to find it, and keep it fixed, as the English do with their things, forevermore; it is passing, glancing, gesticular; it is a traveller, a newness, a surprise, a secret which perplexes them, and puts them out.
    Ralph Waldo Emerson (1803–1882)

    Red lips are not so red As the stained stones kissed by the English dead.
    Wilfred Owen (1893–1918)
