Well the longest word That I came across in English Is when I was in class 7th that is in 1981.It was the outcome a debate that ensued between two of my teachers. The word actually is a combination of a lot of prefixes and suffixes . Well the word is ''Antidisestablishmentarianism" which tells about the act to prosecute all those who don't believe in any establishments.
