Clarification Edit: for people who speak English natively and are learning a second language
Don’t forget that there once was a time when smart people just added letters to words that don’t do anything - like the b in debt, which was called det before. Or when America got rid of Britains U after O because newspapers charged per letter.
British newspapers were only able to subsidize the use of the letter ‘u’ through taxes levied on the colonies, which led to the revolution. So who’s so smart after all?
Nah, seriously, the Normans added the ‘u’ to French-derived words after they invaded. English orthography wasn’t standardized, though. Johnson kept the ‘u’ out of a sense of tradition when compiling his British dictionary, and Webster elided it in his American dictionary because we don’t pronounce it. Neither spelling, -or or -our, derives from the other.
