The Fourth method: Definition a dictionary will give you two different definitions of the word definition: ( \a statement of what a thing is\and(2)a\a statement or explanation of what a word or phrase means or has meant. \ In the strict sense a definition as we shall use the word here is not of a thing. but of a word or of a process The process of making a definition is not, however, a mere game of words. It is clear that we cannot make a usefu
