Here's why:
* Words can be broken down: Words are not always the smallest unit of meaning. For example, "unbreakable" has three parts: "un" (not), "break" (the action), and "able" (capable of). Each of these parts contributes meaning to the overall word.
* Morphemes are meaningful: Morphemes are the smallest units that carry a distinct meaning. They can be individual words, like "dog," or parts of words, like the prefixes "un-" or "re-" or the suffixes "-ing" or "-ly."
Here's a simple example:
* "Unbreakable"
* un-: not
* break: to separate
* -able: capable of
