Fast Swahili–English dictionary that handles verb and noun prefixes properly.
Details
The dictionary most Swahili learners settle on, because it copes with the language's morphology: paste in an inflected form like 'wamekwenda' and it finds the root instead of failing. It is free, quick and free of clutter. Entries are terse, with no example sentences or audio, so use it for lookups rather than for learning how a word behaves.
