Inflectional morphemes are suffixes that change the grammatical use of a word, but not its meaning. For example, adding "-s" to "book" makes it plural, but it doesn't change the word's meaning. 

Examples of inflectional morphemes: 

• -s: Used to make nouns plural, as in "dogs"

• -ed: Used to make verbs past tense, as in "waited"

• -ing: Used to make verbs present participle, as in "eating"

• -en: Used to make verbs past participle, as in "eaten"

• -er: Used to make adjectives comparative, as in "teacher"

• -est: Used to make adjectives superlative, as in "smallest"

• -'s: Used to make nouns possessive, as in "dog's"
