Here is a link to an Afrikaans search engine: Rieme.co.za. Some of you may find it useful!
It also has a page – WOORDEBOEK – where you can use to translate words into English or Afrikaans. It is in no way comprehensive but it useful for some words, give it a try. However, I would advise to invest in a nice Eng/Afr dictionary if you need it frequently.
