【正确答案】正确答案：Inflection is the manifestation of grammatical relationship through the addition of inflectional affixes, such as number, person, finiteness, aspect and case, which do not change the grammatical class of the stems to which they are attached. For example, the past form of the verb work is realized by the addition of the inflectional suffix; "-ed"; the plural form of the noun child is realized by the inflectional suffix; "-ren".
