This extensive, well-researched and clearly formatted lexicon of a wide variety of linguistic terms is a long overdue. It is an extremely welcome addition to the bookshelves of sign language teachers, interpreters, linguists, learners and other sign language users, and of course of the Deaf themselves.
Unique to this lexicon is not only the inclusion of many terms that are used especially for sign languages, but also the fact that for the terms, there are not only examples from spoken languages but there are also glossed and translated examples from several different sign languages.
There are many interesting features to this lexicon. There is an immediate temptation to find examples of terms in the sign language one is studying as well as determining how many of the most used concepts would be signed in the local language. As there are to date still almost no reference grammars of sign languages, the definitions of many of these concepts would be extremely helpful for those linguists planning to make a reference grammar of their sign language.
