Google Dictionary is the service in news that has been closed now. You can not access this service by visiting the Google dictionary page link. Instead, it will show you “Google Dictionary is no longer available.”
There is a reason of removing that. Making a separate page for meanings is unnecessary if you can integrate the same as tool into web search results. Now, that same feature is embedded in the left sidebar of Google’s web search. Type a word and click on the ‘Dictionary’ link on the left sidebar under ‘More Search Tools’ and you will find the same results of previous dictionary.
The popularly used chrome extension for Google dictionary will continue to work in the same way or it will be stopped working that is still not clear. If it becomes inactive, more people would feel uneasy in opening a new tab each time to look for a word.
