Ask HN: What do you think about this idea, Queryable Words

I have an idea for a side project for a month now, wanted to get some feedback before I set out to coding. I want to create a tool where you can query English words, so for example, if your query is: fruits that are 5 letters, then you'll get words like apple, mango, etc. I also imagine this tool would be crowd sourced so that database would be updated constantly.

Other queryable features might include part of speech, number of syllables, language of origin, what it rhymes with, what letter it starts with, synonyms. Do you guys think this would be useful? Any suggestions? Thanks folks.
