(FLOK-si-NO-si-NY-HIL-i-PIL-i-fi-KAY-shuhn)
This word was coined by combining four Latin terms flocci, nauci, nihili, pili, all meaning something of little or no value, which were listed in the well-known "Eton Latin Grammar" of Eton College in the UK.
The Oxford English Dictionary shows the first use of the word by William Shetstone in 1777
