* Marvellously: This word is an adverb meaning "wonderfully" or "amazingly," and while it doesn't directly come from "mar," it shares a common origin with the word "marvel," which is related to "mar" in the sense of "wonder" or "surprise."
* Remarkably: This word means "in a remarkable way" and is often used to describe something that is noteworthy or surprising. While not directly from "mar," it's related in the sense of "remark" which can be understood as something that stands out or draws attention, just as a "mar" could be a flaw or imperfection that stands out.
It's important to note that these words aren't technically formed from the root "mar" but rather from related words. However, they illustrate the concept of how a root word can be associated with various meanings that can influence the formation of related words, even if those words don't directly include the root.
