Words in the Mind: An Introduction to the Mental Lexicon

I have studied a lot of subjects in my time and some of the most boring have been written in the area of linguistics. Words in the Mind is not only an exception but I would go so far as to say that it is perhaps one of the most stimulating texts on any academic subject. Indeed, if you like poetry, which I don't, you'll like it even more than I did.

It makes a good job of combining ideas from cognitive psychology (also not usually the most readable of subjects) with linguistics. Entertaining and informative, whilst incorporating important and up to date research, I found this most readable.
