Are suffixes and bound morphemes synonyms?

While suffixes are a type of bound morpheme, they are not synonymous. Here's the breakdown:

* Bound morphemes are units of meaning that cannot stand alone as words. They need to be attached to other morphemes (free or bound) to create a meaningful word.

* Examples: "un-", "-ing", "-ly", "-s"

* Suffixes are a specific type of bound morpheme that are added to the end of a word to change its meaning or grammatical function.

* Examples: "-ing", "-ly", "-s"

Therefore, all suffixes are bound morphemes, but not all bound morphemes are suffixes.

Think of it this way:

* Bound morpheme: The broader category, like "fruits."

* Suffix: A specific type of fruit, like "apples."
