The longest word in the English language...

No, it's not "antidisestablishmentarianism" ("opposition to the separation of the established church and state" - that is a good Tea Party word, eh?),  nor "supercalifragilisticexpialidocious". (which literally means "repentant for the utmost and fragile beauty yet highly teachable", yet practically means "very wonderful").  Good guesses, though. 

If you suffer from hippopotomonstrosesquipedaliophobia, then perhaps you shouldn't continue reading this post, as I don't want you to freak out.  Take a hike, if you're near Webster, Massachusetts, maybe to Lake  Chargoggagoggmanchauggagoggchaubunagungamaugg, (Native American for "You fish on your side; I fish on my side; nobody fish in the middle," as Richard Lederer puts it).  If you are in England then you could go to the famous and relaxing spas at Bath, which are restorative and also  aequeosalinocal -calinosetaceoaluminosocupreovitriolic.  If you like to fish, then perhaps you could go to Hawaii and see if you can catch some humuhumunukunukuāpuaʻa.  

Or if you like Greek cuisine you may want to invite a bunch of your friends over and try dining on lepadotemachoselachogaleokranioleipsanodrimhypotrimmatosil

James Joyce was fond of long words, and used them in his books.  He gets credit for using or inventing -  bababadalgharaghtakamminarronnkonnbronntonnerronn

If you feel this is not a case of floccinaucinihilipilification, then you are truly a logophile.   Ready for the longest word?  There are many scientific and medical words that are very long.  But the longest in the English language is chemical.  Tryptophan synthetase A, as its friends call it, is an enzyme.  It has 267 amino acids, included in its full name, which brings it to 1,913 letters.  Forgive me if I misspelled it, but when I ran it through my spellchecker it blew up.  Take a deep breath:
