Where can I found a list of all the words in Hebrew including plurals, inflections, etc.? I have only found some lists that are based on wikipedia corpus or subtitles curpus, which include many errors and are missing so many words. (http://invokeit.wordpress.com/frequency-word-lists/)
You haven't mentioned, which Hebrew you mean and what format you expect. Presuming, you are interested in the Modern Israeli Hebrew and that the format is not so important, the best choice would be (Hebrew-Hebrew) Even-Shoshan Dictionary: it includes both words in vocalized form and in ktiv male; plural and smikhut forms are provided for nouns, and basic inflected forms - for verbs.
There are scanned versions of the 1979-edition on the web and there is an electronic version from babylon, but it's for money.
