Here's a breakdown:
* Root words are often the base of many other words. For example, the root word "port" (meaning "to carry") is found in words like "transport," "import," and "export."
* They can be single words or parts of words. For instance, "scrib" is a root word meaning "to write" found in "scribe," "describe," and "inscription."
* They can come from different languages. Many English root words come from Latin and Greek.
