Almost all of the languages in the world come originally from either Greek, Latin or Aramaic as these are some of the oldest languages in the world, this is why they all have similar roots.
Explanation:
Maximum languages of Europe refer to the Indo-European language class. Out of a whole population of 740 million (as of 2010), some 94% are local speakers of an Indo-European language, within Indo-European, the three largest phyla are Slavic, Germanic, and Romance, with more than 200 million orators each, between them, considering for close to 90% of Europeans. Miniature phyla of Indo-European located in Europe include Hellenic.
Europe's diversity is really low.Therefor if they didnt have so many languages then they wouldn't all understand many people. their population is over 700 they all cant talk the same language so they made it all similar
