What is the longest English word? |
We do have genuine (if rather obviously deliberate) examples in our files of antidisestablishmentarianism (28 letters) and floccinaucinihilipilification (29 letters), which are listed in some of our larger dictionaries. Other words (mainly technical ones) recorded in the complete Oxford English Dictionary include:
otorhinolaryngological (22 letters),
immunoelectrophoretically (25 letters),
psychophysicotherapeutics (25 letters),
thyroparathyroidectomized (25 letters),
pneumoencephalographically (26 letters),
radioimmunoelectrophoresis (26 letters),
psychoneuroendocrinological (27 letters)
hepaticocholangiogastrostomy (28 letters),
spectrophotofluorometrically (28 letters),
pseudopseudohypoparathyroidism (30 letters).
Most of the words which are given as 'the longest word' are merely inventions, and when they occur it is almost always as examples of long words, rather than as genuine examples of use. For example, the medieval Latin word honorificabilitudinitas (honourableness) was listed by some old dictionaries in the English form honorificabilitudinity (22 letters), but it has never really been in use. The longest word currently listed in Oxford dictionaries is rather of this kind: it is the supposed lung-disease pneumonoultramicroscopicsilicovolcanoconiosis (45 letters).
In Voltaire's Candide, Pangloss is supposed to have given lectures on metaphysico-theologo-cosmonigology (34 letters). In Thomas Love Peacock's satirical novel Headlong Hall (1816) there appear two high-flown nonce words (one-off coinages) which describe the human body by stringing together adjectives describing its various tissues. The first is based on Greek words, and the second on the Latin equivalents; they are osteosarchaematosplanchnochondroneuromuelous (44 letters) and osseocarnisanguineoviscericartilaginonervomedullary (51 letters), which translate roughly as 'of bone, flesh, blood, organs, gristle, nerve, and marrow'.
Some editions of the Guinness Book of Records mention praetertranssubstantiationalistically (37 letters), used in Mark McShane's Untimely Ripped (1963), and aequeosalinocalcalinoceraceoaluminosocupreovitriolic (52 letters), attributed to Dr Edward Strother (1675-1737).
This kind of verbal game originates, so far as records attest, with the ancient Greek comic playwright Aristophanes, inventor of Cloud-Cuckoo-Land (Nephelokokkygia).
The formal names of chemical compounds are almost unlimited in length (for example, aminoheptafluorocyclotetraphosphonitrile, 40 letters), but longer ones tend to be sprinkled with numerals, Roman and Greek letters, and other arcane symbols. Dictionary writers tend to regard such names as 'verbal formulae', rather than as English words
What is the name for a sentence that contains all 26 letters of the alphabet? |
These things are called pangrams, and the most famous is the one typists use to test their keyboards: The quick brown fox jumps over the lazy dog. We don't know of a sentence that only uses each letter once, but there is a 28-letter example that uses the letters "i" and "u" twice: Brick quiz whangs jumpy veldt fox.
What comes after primary, secondary, tertiary? |
The sequence continues with quaternary, quinary, senary, septenary, octonary, nonary, denary. Words also exist for `twelfth order' (duodenary) and `twentieth order' (vigenary).
Chemical Terms
Two chemical terms (3,641 and 1,913 letters long) have appeared in the Guinness Book of World Records. They were withdrawn because they have never been used by chemists, and there is no theoretical limit to the length of possible legitimate chemical terms. A DNA molecule could have a name of over 1,000,000,000 letters if it was written out in full.

(45) PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS (also spelled PNEUMONOULTRAMICROSCOPICSILICOVOLCANOKONIOSIS) = a lung disease caused by breathing in particles of siliceous volcanic dust.
This is the longest word in any English dictionary. However, it was coined by Everett Smith, the President of The National Puzzlers' League, in 1935 purely for the purpose of inventing a new "longest word". The Oxford English Dictionary described the word as factitious. Nevertheless it also appears in the Webster's, Random House, and Chambers dictionaries. (37) HEPATICOCHOLANGIOCHOLECYSTENTEROSTOMIES = a surgical creation of a connection between the gall bladder and a hepatic duct and between the intestine and the gall bladder.

Interestingly the most common letter in English, E, does not appear in this word at all, whilst I occurs a total of nine times. The word dates back to 1741. The 1992 Guinness Book of World Records calls floccinaucinihilipilification the longest real word in the Oxford English Dictionary, and refers to pneumonoultramicroscopicsilicovolcanokoniosis as the longest made-up one.

I marvel thy master hath not eaten thee for a word;
for thou art not so long by the head as
honorificabilitudinitatibus: thou art easier
swallowed than a flap-dragon."Shakespeare does not use any other words over 17 letters in length. (27) ELECTROENCEPHALOGRAPHICALLY
