which is the longest word in the dictionary?

Pneumonoultramicroscopicsilicovolcanoconiosis (Pneumonoultramicroscopicsilicovolcanoconiosis is, according to the Oxford English Dictionary, “a factitious word alleged to mean ‘a lung disease caused by the inhalation of very fine silica dust usually found in volcanoes’.” It was coined to serve as supposedly the longest English word. The more general and widely used term for this condition is pneumoconiosis, also known as black lung disease.

If you own the Webster dictionary, the longest word is

Floccinaucinihiliphilipication (Check spelling)

If you don’t find this word, go to your local library, and contact the reference section.

the longest word in any of the major English language dictionaries is pneumonoultramicroscopicsilicovolcanoconiosis, a 45-letter word which refers to a lung disease contracted from the inhalation of very fine silicious particles.

NO, ‘which’ is not the longest word in the dictionary.
