Glossary

Another important thing is Glossary. This can be extended in this forum too:

For a really good glossary (provided you speak/read french…) there is always the one by André Pascual:

If someone were to have a lot of time on his hands, it could be made into a Blender glossary (updating to the Wiki of course…)
