"Pathology of the word, or damage to certain words in the process of use" is an outstanding work of the famous French lexicographer and philologist Emile Littre. In this book, the author analyzes the phenomena that he calls "lesions", that is, the loss of the meaning of words or even a change in their meaning in the process of use. Littre examines linguistic anomalies and errors that may arise from the incorrect use or understanding of words, and also considers the influence of sociocultural context on linguistic phenomena. This book is not only an interesting linguistic study, but also a useful resource for anyone interested in language, its development and functioning in society.
