4. Afrikaans
This is not a very famous language, considering the fact it is only spoken in some African countries, such as Namibia and South Africa. However, that is not the reason not to try and learn it, since it is estimated that it can be learned for, 23-24 weeks, that is, 575-600 hours, being in the first category. Some of the words are quite similar to English, and for me, the most appealing was the fact that Nadine Gordimer, a writer, political activist and Nobel Prize winner spoke it. Considering the number of hours it requires, Afrikaans is the fourth easiest Germanic language to learn for English speakers.
