isiZulu.net is a hobby project trying to build a reasonably useful, modern Zulu-English online dictionary that anyone can contribute to. Beyond bidirectional word search, it offers automatic morphological decomposition, conjugation and phonetic transcription of Zulu words, translation of simple Zulu and English phrases, spell checking, and grammar and pronunciation basics.
If you mention the dictionary in a paper, lecture etc. I'd be happy to receive an advance copy along with your comments.
isiZulu.net is used as a reference work in the evaluation of a Lëtzebuergesch-German online dictionary at the AFRILEX Conference 2012.
You can add isiZulu.net as a search engine to browsers supporting OpenSearch (e.g. Firefox).
The dictionary offers a REST interface that returns JSON data. To use it you need an API key that you can request by e-mail.
There will be a talk about isiZulu.net given at the AFRILEX Conference in July. A Quantum of Fame. :-)
By popular demand there is now a mobile website as well.
