INFLECTION AND SYNTAX
CHAPTER I
INFLECTION
52. Inflection is a change of form in a word indicating some change in its meaning. A word thus changed in form is said to be inflected.
Thus the nouns man, wife, dog, may change their form to man’s, wife’s, dog’s, to express possession; or to men, wives, dogs, to show that two or more are meant.
The pronouns I, she, may change their form to our, her.
The adjectives large, happy, good, may change their form to larger, happier, better, to denote a higher degree of the quality; or to largest, happiest, best, to denote the highest degree.
