Language change: progress or decay

You will often hear complaints that new forms of language usage represent degeneration, reducing our ability to express ourselves accurately. But how much is language change to be feared? In Language change: progress or decay? Jean Aitchison shows that language change has always been happening, and is not the bugbear that many seem to think.

Aitchison looks at how social pressures can change the way we speak, either trying to appear more cultured, or in adopting more traditional ways of speech. She shows how language often changes in a predictable way, with simplification of words that are hard to say, followed by a process of regularization, trying to make a language seem more consistent. She considers how the speech of children, and of those with language disorders, differs from normal speech, but argues that these differences don't play much of a role in more general language change. There are also chapters on how words can change their meaning, and on the birth and death of languages.

The conclusion is that language change is not the process of decay that many fear. However, I felt that there are some things which the book doesn't really address. For instance, how much does the huge amount of material in written form slow down the process of language change. Aitchison also indicates that she thinks the politicization of language to be more of a problem than language decay, but doesn't go into detail. So the book might not answer all of your questions, but it does provide and interesting and informative introduction to language change, written in a way that is accessible to those with no previous experience in studying linguistics.

Product Description
This book gives a lucid and up-to-date overview of language change, discussing where our evidence about language change comes from, how and why changes happen, and how languages begin and end. It considers both changes that occurred long ago, and those currently in progress. This substantially revised third edition includes two new chapters on change of meaning and grammaticalization. New sections have been added to other chapters, as well as over 150 new references. The work remains nontechnical in style and accessible to the reader with no previous knowledge of linguistics.
