I am writing this in English because the chances are if you’re reading this page then you want to speak Afrikaans but don’t already. There are a number of places in London offering Afrikaans it seems. Let me know how you find these courses or if you know of anywhere else and I’ll add a link.

Wikipedia
I think the Afrikaans Grammar page on Wikipedia is really good. It’s quite brief but for a learner there is some really good information on here to help in the beginning. I refer to the Afrikaanse Grammatika page quite a bit and still learn new things.

Duolingo
Duolingo has not released an Afrikaans yet despite the many threads asking for one, but I am adding it for three reasons; one, I use it every day and it has the potential for any language to make a real impact because it is a great way to learn while using other methods; two, the more people push for an Afrikaans course then the more likely we are to get one; and three, I have completed the Dutch course and even after many years of learning Afrikaans this has still helped me learn things for Afrikaans.

Easy Afrikaans
Easy Afrikaans has some useful pages with good descriptions, explanations and sound files.

WikiHow – Learn to Speak Afrikaans
I think How to Learn to Speak Afrikaans from wikiHow is a pretty decent resource. It is succinct and offers some really good ideas which I use, and a good explanation about the context of Afrikaans and South Africa.

Learn 101 Afrikaans
Learn Afrikaans from learn101.org has some pretty decent advice and thorough grammar coverage. I don’t use online learning as much as I use books, but this is worth looking through in detail.

AfrikaansPod101
Afrikaanspod101 is downloadable if, like me, you listen to a lot of podcasts. Good for audio (well obviously) but I do want to stress the importance of active listening and not just listening passively – or just hearing as might be more accurate to say – while doing something else and then hope to absorb the information.

IGCSE Afrikaans
You can study for the IGCSE Afrikaans – Second Language internationally through University of Cambridge International Examinations and the course books are available on Amazon and Kalahari.

School of Oriental and African Studies
The School of Oriental and African Studies (SOAS) in Russell Square offers an Afrikaans course every year. The three-term course starts in September every year. Each term costs £235. Ring SOAS on 020 7898 4888 for more information or email languages (at) soas.ac.uk.

Language Studies International off Tottenham Court Road runs a 10-week Afrikaans evening course for beginners offering 20 hours of tuition. The course costs £235.00 per person. If you’re interested, ring 020 7467 6515. They often advertise on Gumtree.

A general language learning site that is well worth a visit is How To Learn Any Language. Although its focus is on learning languages, there are sometimes threads on Afrikaans and the archived threads are very interesting.
