Why do we have long words? Does sesquipedalia–a long word for long words–really have a use? Well, for those of us who find such words senseless and completely worthless, you might say we have a disposition for… floccinaucinihilipilification.
This 29-letter word, which means “to estimate something as having no value,” is entirely derived from Latin, coming from the roots floccus for wisp, naucum for trifle, nihil for nothing, and pilus for hair. Put together, this word denotes the process of becoming useless, as the roots all connote a lack of grandeur.
If one wishes to bestow a floccinaucinihilipilification upon an item, one is to floccinaucinihilipilificate.
