Answer 2

Yes, like the other languages, Portuguese has undergone a historical evolution, being influenced by several languages and dialects, until reaching the stage known today. It must be considered, however, that today's Portuguese comprises several dialects and sub-dialects, often quite distinct, speaking, and sub-standard, as well as two internationally recognized standards (Brazilian Portuguese and European Portuguese). At present, Portuguese is the only language in the western world spoken by over one hundred million people with two official spellings.
