Duplicate post with different title

I’m using wordpdress posts like a kind of a dictionary of a specific subject terms and there definitions. now sometimes i have different names used for the same thing and i want all the different names to appear in the site’s alphabetical posts list but they will all direct to the same post so if i edit the post i dont need to edit each post (for each different name used).

I hope i explained my self well.

What i look for (i think) is the ability to have multiple titles for the same post… or some other way that will let a post count like different posts in the posts archives but in reality be just one post.

Any Idea?

Thanks,
Ben
