I am looking for a software which I can host in popular and general shared web hosting services(online softwares like wordpress, meidawiki, drupal etc.) which can do the following-

1. allow users to create account
2. allow users or anons to add words to the dictionary (there will be English as base language and other languages)
3. easier way to import all the words from English dictionary
4. users should be able to write the that language equivalent of the English word
5. Every word should have it's own address and page like www.namesomething.com/word/en/software will contain the word software and the other language word for it
6. search should be faster and should find nearer results
7. it's should be able to list related words like if the user is looking at "software" then other words from s like "softcopy" etc should appear alphabetically in that page
8. Any one should be able to comment on the word which is not seen in the main page but other page similar to the talk page in the wiki
9. any one should be able to contribute
10. clean interface unlike wiki (media wiki and all other) just for words only

I tried media wiki and other wiki software but it overloaded and unclean. I am looking for interface similar to oed.com but clean, minimal as we are not going to have such more information. Just words in English and it's other language equivalent. Here we are talking about a language which has not yet been in the Internet. It's should be collaborative.
