Taking it as a riddle, the biggest word is "SMILES" because there is distance of a mile between two S.\nAcamedically, the biggest word in English is PNEUMONO­ULTRA­MICRO­SCOPIC­SILICO­VOLCANO­CONIOSIS (45), a lung disease. Oxford takes it as factitious.\n2nd biggest is HEPATICO­CHOLANGIO­CHOLECYST­ENTERO­STOMIES (37)

Agree with some of the choices posted by others. \n\nHere is my two cents worth and some trivia: \n\nFYI - Floccinaucinihilipilification is the longest word used in a commercial.  An insurance company (Geico?)commercial used this word in a spelling bee scenario.  All the kids are stunned. Even the judge seems baffled trying to use it in a sentence. The insurance company pledge, "No Hard Words".  See a link below for the word history.\n\nBut as mentioned in that link,"..(it was the longest in the first edition of the Oxford English Dictionary but was supplanted by pneumonoultramicroscopicsilicovolcanoconiosis in the second)...\n\nRegarding US Standard Dictionaries, at 45 letters long (45p) it appeared in the Webster's Third New International Dictionary, the Random House Dictionary of the English Language, Unabridged, and the Merriam-Webster's Collegiate Dictionary.\n\nSee Wiki source for the word origin.

The longest word in any major English language dictionary is\npneumono­ultra - ­micro­scopic­sili - co­volcano­coniosis, a 45-letter word supposed to refer to a lung disease, but research has discovered that this word was originally intended as a hoax. It has since been used in a close approximation of its originally intended meaning, lending at least some degree of validity to its claim.\n\nThe Oxford English Dictionary contains pseudopseudo - hypoparathyroidism  (30 letters).\n\nThe longest non-technical word is \nflocci­nauc - i­nihili­pili­fication at 29 letters. Consisting of a series of Latin words meaning "nothing" and defined as "the act of estimating something as worthless," its usage has been recorded as far back as 1741. In recent times its usage has been recorded in the proceedings of the United States Senate by Senator Robert Byrd, and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically.\n\n(Words hypenated because Yahoo was shortening them by cutting it off and using ...)

It is, in fact, Supercalifragilisticexpialidoc ious (space because it cuts me off otherwise).  That's what I thought, but I figured I'd better check...just in case.\n\nInterestingly, the longest common phrase is: ship-towed long-range acoustic detection system.\n\nI just discovered the other answer, and...wow.  I took this way, way too seriously.

The longest *actual* word in the English language is Antidisestablishmentarianism (supercalafragalisticexpecialadocious does not count, seeing as it is not a real word)

Biggest generally will mean 'Land-area'-wise, therefore the answer is Russia..\n"Largest" would mean the 'Population'-size, and that answer is China

That's not true. The official longest word is over 64,000 characters long. It is theoretical mature protein compound.

The Oxford English Dictionary is the largest dictionary of any language in the world.  It contains approximately 1.5 million entries and includes, arguably, every word used in English since about 1500.  Some entries, such as acersecomic, are of words that were used only once in the history of the language, but each word includes every meaning and shade of meaning the word has ever had along with representative quotations illustrating the meaning.

The great thing about the Dutch language, you can stick different words together to make a very big word. A big word I like is:\nHottentottententententoonstellingsmakersopleidingsprogramma\nbut this one is definitely not the largest

Omit "most," then use the superlative form of "big," which is "biggest."
