"We must realize the extent to which it is necessary that our knowledge of language be based on history. Only history can impart to words that degree of precision which we need in order to understand them well."

“Bréal, Michel Jules Alfred, in: Encyclopædia Britannica, Volume 4, 1911.”

“There is a constant succession of books on the subject of comparative grammar, for the use both of students and of the general public; yet it does not seem that we are offered what we really need. Language is full of lessons for those who know how to question it. Through all the centuries humanity has deposited in Language the acquisitions of material and moral life. But it must be approached from the side on which it appeals to the mind. If we limit ourselves to the changes of vowels and consonants, the study is reduced to the proportions of a merely secondary branch of acoustics and physiology; if we think it enough to enumerate the losses undergone *by the machinery of grammar, we give the impression of a building that is falling into ruins ; if we confine ourselves to vague theories on the origin of Language, we merely add an unprofitable chapter to the history of systems.”

“In modern society, the meaning of words changes much more quickly than it did in antiquity or even in the recent past. This arises from the intermingling of social classes, the struggle of interests and opinions, the struggle of political parties and the variety of aspirations and tastes.”

“There is another kind of studies which distinguished from the sometimes opposed to comparative grammar. It is known under the name of general or philosophical grammar , whose principles and observations were articulated by Port Royal and which deals with the relation of the form of language to the operations of the mind.”

“Sometimes is a synonym which extends itself, and contrasts by just much the domain of its colleague. At other times it is an historical event which comes to modify and renew the vocabulary.”

“In that second part we propose to investigate how it happens that words, once created and endowed with a certain meaning, extend that meaning or contract it, transfer it from one group of notions on to another, raise its value or lower it, in a word — bring about changes. It is this second part that constitutes semantics, i.e. science of meaning.”
