End Matched:  Tongue and groove on both ends of the board.  This offers big savings on materials and labor, by not having to measure and cut every board to fall on a stud. You measure and cut only once per row and the piece you cut off, is the starter piece on next row.

Face Width:  The width of the board that "shows" after it has been put up.  The actual width of the board might be larger due to a "tongue" that is counted in the actual width, but which you don't see when it is connected into the "groove" on another board.  This can be very confusing to people not familiar with buying wood.  To get around this confusion, simply ask your vendor when they give you measurements if they are "overall width," or "face width."

Kiln Dried: This means that the product that is identified as "kiln dried" is wood that has been dried in a giant oven so that its moisture content is between 6%-9%.

Take Off:  Figure price and specs of materials for home or building from the blueprints or plans of the project.

Tongue and groove joint:  A joint formed by the insertion of the “tongue” of one wood member into the “groove” of the other; modifications include tongue and groove rabbet joint, dado tongue and rabbet, tongued shoulder joint, dado and rabbet joint, dado and lip joint.
