Answer 1

Answer 2

The longest word in any major English language dictionary is pneumono­ultra­micro­scopic­silico­volcano­coniosis, a 45-letter word that refers to a lung disease contracted from the inhalation of fine silica dust. 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.[1]

The Oxford English Dictionary contains pseudopseudohypoparathyroidism (30 letters).

The longest non-technical word in major dictionaires is flocci­nauci­nihili­pili­fication 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.[2][3][4] In recent times its usage has been recorded in the proceedings of the United States Senate by Senator Robert Byrd [5], and at the White House by Bill Clinton's press secretary Mike McCurry, albeit sarcastically.[6]
