Which term describes a bound morpheme, often of Latin origin, used to form related words?

The term that describes a bound morpheme, often of Latin origin, used to form related words is actually a suffix. A suffix is a morpheme that is added at the end of a word to modify its meaning or to create a new word altogether. For example, the suffix "-tion" can be added to the verb "inform" to create the noun "information."

Bound morphemes cannot stand alone as words; they must be attached to a base or root. While roots can be bound or free morphemes, suffixes specifically refer to those bound morphemes that come after the base word.

It's important to consider that prefixes, which are also bound morphemes, come at the beginning of words, and while they do serve a similar function in word formation, the question specifically asks for a term typically used at the end of the word. Thus, identifying suffixes as the correct answer aligns with the definition provided in the question.
