"free morpheme"的定义和意义

What is a "free morpheme"?

A free morpheme is a type of morpheme that can stand alone as a word and convey meaning without needing to be attached to a base or root. They can be simple words, like "cat" or "run", that do not require any additional elements to express a complete idea. Free morphemes are fundamental to language because they serve as the building blocks for more complex expressions and contribute to the overall vocabulary of a language.
