Inflectional Morphemes
【正确答案】：An inflectional morpheme is an affix that indicates aspects of the grammatical function of a word, such as -s for plurality of countable nouns, -ed for past tense of verbs, -er and -est for the comparative and superlative degrees of adjectives or adverbs. An inflectional morpheme does not form a new word when it is added to another word, nor does it change the part of speech of the word to which it is affixed.
