Bloom filter: That&#x27;s assuming your vocabulary is reasonably finite. <a href="http:&#x2F;&#x2F;www.ling.helsinki.fi&#x2F;~fkarlsso&#x2F;genkau2.html" rel="nofollow">http:&#x2F;&#x2F;www.ling.helsinki.fi&#x2F;~fkarlsso&#x2F;genkau2.html</a> has a list of forms for a single finnish noun. That&#x27;s including case, possessives and clitics, but you can also have compounding (eg. several nouns in a row as one word) and derivations into other parts of speech (verbs become nouns etc). And once you&#x27;ve found out it&#x27;s misspelt, you need suggestions..
