The English language is a constantly evolving. New words are constantly being added. Even the alphabet is not immutable. For example did you know that not so long ago there were 27 letters on the alphabet ?
A lot of what we ‘know’ to be true can sometimes turn out to be no more than an ‘urban legend’. Did the Nazi’s invent Fanta ? Does ‘Colgate’ means ‘go hang yourself’ in Spanish ? Can you tell whether they’re fact or fiction ?
