I don't recall a specific place where the terrain is described in detail, although a lot of it is described throughout the documentation depending upon the relevant topic (for instance Fortification is described in the "Firing > Fortifications Protection" section of the Users Manual). Hopefully most of it should be fairly intuitive, but feel free to query the forum if you come across a term you aren't sure of. "Primary" indicates a primary road.
You can find out specific movement costs for each terrain type by opening up the specific scenario you are interested in playing, then from the menu select "Help" and then "Parameter Data". This will bring up a dialog box which has sections detailing the movement costs for each type of terrain. Note that movement costs are generally cumulative.
For instance, if you open the ES: Busy Bosses scenario and then open the "Parameter Data dialog box, you will see in the "Movement Cost: Infantry" section that it says "Primary: 3 MP", which means it costs 3 movement points to move along a primary road. Further down in the "Movement Costs:" section, it says Elevation Cost: 12 MP per 10 meters. Therefore in the Busy Bosses scenario, moving from hex 12,6 to hex 12,7 will cost 15 movement points (3 for moving along the primary road and 12 for moving up 10 meters in elevation).
Answering your follow-up question, road movement does not negate the cost to climb in elevation, however it can leave you with enough movement points to continue moving further, whereas often you can only move up a single hex when moving up elevation levels in other types of terrain.
Also note that other factors will affect your movement points; such as whether you are in Ground Mode, whether you are overloaded (for instance, carrying Satchel Charges in addition to your normal weapons), etc.

I know that the PDT contains movement costs, but I can't seem to find in the manuals a verbal description of the various terrain types. For example: Playing Busy Bosses against AI in ES. There are these things which pass through certain hexes called "Primary."

But that does not seem to be the case. So, finally, the question: Is there anywhere I can go to get a verbal description of the terrain features?
