Examples:

Did you know?

The Latin word suffundere, ancestor to suffuse by way of Latin suffūsus, has various meanings that shed light on our modern word, among them "to pour on or in (as an addition)" and "to fill with a liquid, color, or light that wells up from below." It’s no surprise, then, that suffuse refers to the action of fluid or light spreading over or through something, as when light fills a dark room when you crack open a door. Suffundere is a blend of the prefix sub- ("under" or "beneath") and the verb fundere ("to pour" or "to send forth"). Other English verbs related to fundere continue the theme of pouring or spreading: [diffuse](https://www.merriam-webster.com/dictionary/diffuse) ("to pour out and spread freely"), [effuse](https://www.merriam-webster.com/dictionary/effuse) ("to pour or flow out"), [transfuse](https://www.merriam-webster.com/dictionary/transfuse) ("to cause to pass from one to another"), and the verb [fuse](https://www.merriam-webster.com/dictionary/fuse) itself when it's used to mean "to meld or join."
