Sentences Website

Hi, I am trying to seek a website that enables you to key in a word and forms up multiple sentences to show you how they actually fit in.

It was a very useful site and unforturnately I have lost it a while ago. Was wondering if anyone of you know of any similar sites. All it is, is that it works like a dictionary but instead of the meaning popuping up, a few sentences with relevant examples comes up.

Thanks!

It is great for new vocab usage and understanding.
