SOCRATES, Greek Philosopher, 470?-399 BC The beginning of wisdom is a definition of terms. The beginning of wisdom is calling things by their right names.

In 2001 while working for the South Carolina Department of Parks, Recreation, and Tourism as the first State Trails Coordinator I published Trails Primer: A Glossary of Trails, Greenway, and Outdoor Recreation Terms and Acronyms. If you don’t find the word you need, if you know of an important word that is not included, or if you think the definition of a word misses the mark or is lacking in clarity, please email me and I’ll fix it in the next update. I hope that this will be a valuable resource for all who work to develop trails and greenways. This glossary can be read quickly, understood easily, and applied immediately. The definitions have been taken primarily from glossaries and terms found in dozens of trail and greenway publications published in the last forty years. The terms range from the mundane to the highly technical. The end result of this work is a starting point-a list of terms that will get trail managers and advocates thinking about and sharing definitions. Ideally, you will create something new and more suitable by editing and improving upon the definitions found here. This does not pretend to contain the most exhaustive list of terms or the best, most acceptable, or locally appropriate definitions. Spending some time with this list will provide quite an education about the various professions and their terminology. I think that everyone involved with trails and greenway development will find that this is not just a useful list of terms. The definitions clearly point to the intersection of trails and greenway work with numerous other disciplines and professions. The terms are listed in alphabetical order, so definitions of interest can be found quickly.
