In English, the word "comfortable" means the same as "舒适" in Chinese. It comes from the Latin word "comfortabilis," which means "giving comfort or ease."

Here are some examples of how to use "comfortable" in a sentence:

This couch is so comfortable that I could fall asleep on it. (这沙发真舒适，我可以在上面睡着了。)

The room was warm and comfortable, with soft music playing in the background. (房间温暖舒适，背景音乐轻柔。)

I feel most comfortable when I'm at home surrounded by my family. (我最舒适的时候是和家人在家里。)
