This other commenters are just being pedantic and have nothing to add. What you meant was perfectly valid English and there’s no need to explain you meant European languages when discussing European languages. However I do not believe your comment about the “vast majority” of languages is accurate. I indo-European languages make up about half of all languages on the planet (3.2 billion) and no other language family comes close.
