If I were to learn another language, which one should I consider?

It depends on what you want or need. If your job will require you to work with a certain country like Japan, then learn Japanese. If you want to be a pilot, English is required. If you want to travel to a certain country like Greece, learn Greek. English is currently the international language (most companies require it) but that changes. Thirty years ago the international language was French.

I would recommend Dutch, it is really easy to learn if you have a higher understanding of English. It is a mix of English German and French, so from Dutch you can learn German and French more easily as well.

come learn Yoruba is an African language from NIGERIA from a very popular tribe
