What is the best dictionary site on the web and why?

I just normally plug define:text into google. Replace “text” with whatever word or phase you want and it will give results from multiple places on one page.

example

http://dictionary.com

http://dictionary.com is great!

It gives the correct spelling, definition and alternatives if you type in the wrong spelling or don’t even know how to spell the word you are looking for.

http://www.answers.com

http://dictionary.com by far. If you’re actually looking to define words, that is. If you’re looking for more ambiguous definitions, try defining with Google. http://urbandictionary.com is also quite amusing.

I usually use (and like) merriam webster. I use Roget’s Thesaurus for synonyms, etc.

I second google and define:text
If you use Firefox instead of IE (which you most certainly should), you just hit CTRL+K to focus the searchbar, enter define:whatever and hit Enter. Can’t get eny easier than that :-)

I use http://dictionary.com but the popups annoy me, yes they get blocked but the FF/IE bars telling me that annoy me lol.

@Skyrail: The toolbars sort of defeat the point, don’t they?

I love Merriam because you can click an audio icon for pronunciation.
You can open it up in several screens, and create very effective naughty phrases by depressing them in sequence. Example: “you” “are” “a” “big” “butt” “head” is very therapeutic when your boss walks out of the room. Maybe it IS infantile. I don’t care.

@richard: yes they do, just as annoying I swear lol

It’s got to be google. Try this in your search window:
“define: google” I’m sure you’ll learn something new about the company.

It’s not a dictionary site as such, but Visual Thesaurus is pretty cool.
