Some comments on language:
Because of what Notasheep points out, English has the largest and most precise vocabulary of any language on Earth. English is also the most commonly spoken language on Earth. N.B. Mandarin is the most common native language but more people speak English as a first or second language. English is the language in which the World’s business is conducted. It is the global lingua franca of art and science. While English grammar and spelling may seem difficult, English is, in fact, one of the easiest languages for non-speakers to make themselves understood in because the grammar an pronunciation are secondary yo the meaning of the words themselves. Try mispronouncing French to a French speaker. All you’ll get is a blank stare.
After English and Mandarin (which no one outside of Chine actually speaks) the next most commonly spoken language is Spanish. Spanish is very regular and relatively easy to learn. Spanish speakers can understand you even if you mispronounce the words.
French is (or should be) a dying language.
Actually, one of the easiest languages to learn to speak is Japanese. It’s simple and regular. On the other hand, Japanese is probably the hardest language to be literate in – three alphabets.
One of the reasons that Yiddish speakers back in the day were able to learn English so quickly is the similarity of English and Yiddish. For you Yiddish speakers out there, translate the following English sentence into Yiddish: My brother says, “Open the door and thank him for the fish”.
