Portrait of Samuel Johnson Samuel Johnson,  Preface to a Dictionary of the English Language

“ Such is the exuberance of signification which many words have obtained, that it was scarcely possible to collect all their senses; sometimes the meaning of derivatives must be sought in the mother term, and sometimes deficient explanations of the primitive may be supplied in the train of derivation. In any case of doubt or difficulty, it will be always proper to examine all the words of the same race ”

“ Even such derivatives, however, as implying a greater modification of the radical idea than is exhibited by the simplest verbal forms, appear to have been from the first mainly made by means of formative elements, suffixes of derivation, comparable with those which belong to the moods and tenses, and the secondary conjugations of the verb. ”

G. F. Graham,  A Book About Words

“ And herein chiefly lies the value of a knowledge of derivation. For, although a word may now have lost its original meaning, it is of the greatest importance that its primary signification should be known, in order to arrive at a clear knowledge of its exact and accurate modern application. We commonly speak of a man ‘applying’ himself to his work. To the general reader this conveys the idea of giving his mind or attention to what he [99] is about; but to those who are ignorant of the etymology of the word ‘applying,’ the picture of the man bending his body to his task is wholly lost. ”
