Many time asked question: Which is the longest word in the English language? Please do not write place name, technical word or name of any kind of disease. I would like to know the common word which we often used.
The longest word in English depends upon the definition of what constitutes an English word. English allows new words to be formed by construction; long words are coined; place names may be considered words; technical terms may be arbitrarily long. Length can be in terms of orthography and number of written letters or phonology and the number of phonemes.
