longest word in English?

The identity of the longest word in English depends upon the definition of what constitutes a "word" in the English language, as well as how "length" should be compared. In addition to words derived naturally from the language's roots (without any known intentional invention), English allows new words to be formed by coinage and construction; place names may be considered words; technical terms may be arbitrarily long. Length may be understood in terms of orthography and number of written letters, or (less commonly) phonology and the number of phonemes.

I have read the response of the third responder that now I know which is the longest word, but also I would like to have you allow me to give you another longest word in English, which is the word, "SMILES". You see, between the two letters S, there is a mile from one S to the other. lol. Just for fun. Enjoy yourself, my dear friend.
