Here are three of the longest proper words in English I have heard or read in recent days:
– antidisestablishmentarianism meaning to withdraw government support for a particular religion.
– sesquipedalianism meaning the practice of using long, often obscure, words in speech or writing.
– supercalifragilisticexpialidocious is a thirty four letter word and most commonly used to describe something as ‘extraordinarily good’ or ‘wonderful’. Supercalifragilistic is an abbreviation of supercalifragilisticexpialidocious.
Since I was reminded of this word while watching Mary Poppins, at Christmas, here’s a clip of the word being sung in that very same Walt Disney movie.
