isiZulu.net is a hobby project attempting to build a reasonably useful, modern Zulu-English online dictionary that anyone can contribute to. Beyond bidirectional lookups, it offers automatic morphological decomposition, conjugation and phonetic spelling 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).
