Sure, let's break down the morphological structures of the words "unbearable," "international," and "ex-prisoner" and identify the types of morphemes they contain.
"Unbearable":
Morphemes:
"un-" (prefix) - a bound morpheme meaning "not"
"bear" (root/base) - a free morpheme, the core meaning of the word
"-able" (suffix) - a bound morpheme indicating "capable of being"
Types of Morphemes:
"un-" and "-able" are bound morphemes because they cannot stand alone as independent words.
"bear" is a free morpheme as it can exist independently as a word with its own meaning.
"International":
Morphemes:
"inter-" (prefix) - a bound morpheme meaning "between" or "among"
"nation" (root/base) - a free morpheme, representing a country or a people
"-al" (suffix) - a bound morpheme denoting "pertaining to"
Types of Morphemes:
"inter-" and "-al" are bound morphemes.
"nation" is a free morpheme.
"Ex-prisoner":
Morphemes:
"ex-" (prefix) - a bound morpheme meaning "former" or "previous"
"prisoner" (root/base) - a free morpheme, denoting someone held captive
Types of Morphemes:
"ex-" is a bound morpheme.
"prisoner" is a free morpheme.
In each of these words, the prefixes ("un-", "inter-", "ex-") and suffixes ("-able", "-al") are bound morphemes because they cannot function as independent words and are attached to a root word that can stand alone. The root words ("bear", "nation", "prisoner") are free morphemes because they have their own meaning and can exist independently as words.
