It seems like Google has recently removed the dictionary link in search results for at least a portion of users, or perhaps all users, In past, when you searched for a word in the dictionary – for instance “house†– there would be a link leading to a definition in the top blue bar. many years ago this was linked directly to dictionary.com and since January 2005, to answers.com. I think Answers.com will lose a lot of traffic if this feature is removed for all dictionary based words.
I’m not sure why its been removed as I personally used that feature all the time.
Update: Looks like its back up online!
