Great is the English word for "伟大" or "很棒". It is derived from the Old English word "grēat", which means "big" or "large". Here are some examples of how you might use "great" in a sentence:

I had a great time at the party last night. (我昨晚在聚会上玩得很开心)

She is a great singer. (她是一个很棒的歌手)

The book is great. (这本书很棒)

In each of these examples, "great" is used to describe something that is impressive or of high quality. It can also be used to express excitement or enthusiasm, as in the first example.
