„For Bréal, semantics was the science the subject matter of which was study of the cause and structure of the processes of changes in meanings of words: expansion and contraction of meanings, transfer of meanings, elevation and degradation of their value, etc.
Such a delineation of semantics as a branch of linguistics is maintained to this day, for all the differences between the various schools in linguistics. Such degree of uniformity is not confined to the definition of semantics alone. Not all authors give such a definition; some of them approach the issue from a different point of view as regards general classification… but all schools of linguistics engage in the study of the meanings of words and their changes. Thus all of them, in one way or another, engage in semantics as understood by Breal.“
