Open Glossary of terms

As a fairly new user of Tasker, I can tell you it would definitely be helpful if some of you who are in the know could create a glossary of some of the terminology most common to the app.
Possibly even something in a printable format so that it can be kept handy when us newbies are exploring the world of Tasker.
I hope somebody with time can provide this information to make the learning curve a little less steep.
Thanks in advance.
