There were many lingua francas of which French was supposedly the first global lingua franca. That changed and it became English (from what I understand). We will probably see another language become the lingua franca, so my question is: should it be English? Are there better candidates out there? Why / why not?
IMO English is more Germanic than Latin. There’s certainly a lot of latin/french loanwords, but that’s true for all other Germanic languages, too (even if to a somewhat lesser degree). Romance languages like French and Italian are actually derived from Latin and they are a lot different from English but fairly similar to each other (especially Italian, Spanish and Portuguese).
