It means water can get at the wooden structural elements setting on the foundation (as can insects)
You've got even more problems if you're some place here you get snow. The ground will be hard frozen when the snow melts and the only place the melt will have to go is into the building.
It's a bad situation you're going to have to resolve ASAP. Replacing a sill is a serious project.
16inches above grade
3" below grade. To make this more understandable, sketch it on paper. Being at grade is level with the soil, with no sloping. So put a G and a line for "at grade" and draw inches above the top of the foundation to see how it looks: 16 inches down to 11 inches == TOP edge of the Wall. ( Has nice casement windows, providing natural light. Plenty of accommodation given for bushes and plants without interference to windows.) 10 inches down to 6 inches 5 inches down to 0 inches or Ground G ======= AT Grade (Ground), level with the soil== \\Soil grading downward away from structure.\\ 1 inch below 2 inches below 3 inches below ............. The top of your wall would be lower than the outside ground. The foundation could have no windows; they'd be useless even if placed way up at the top. Therefore it would get no natural light. Soil would continually erode at the top edge, meaning, over the years the foundation would appear from the outside even lower than what it is with being below grade. Worse-- no one will be happy with appearance or function.
In laymen's terms, yes. Many people use the terms Slab-on-grade & Floating Slab interchangeably. However, architects, engineers, and construction workers may have a more refined interpretation. Most commonly, a Slab-on-grade construction refers to a foundation in which the a concrete slab (also most commonly thickened at the perimeter) rest directly on grade (aka ground). Where as a Floating Slab foundation refers to a concrete slab resting directly on the grade independently placed within a stem wall (aka foundation wall), which extends down to the depth of the local frost line, running around the entire perimeter. The walls of the building/structure are then built upon this "stem wall". This latter type of construction creates a 'heat bubble' so that the floor is not as subject to the expansion due to frost and secures the structures walls by being supported below the frost line.
Use polyethylene sheet membrane. Prior to concrete placing, cover the entire area with a layer of PE sheet membrane extending the perimeter of slab and up against wall for the depth of concrete.
A or the footing is at the base of the foundation. Usually but not always 3 times the width of the wall. This just make a base for the wall to sit on so that it doesn't push into the ground. Without it, the wall would act as a knife and with the weight of the structure, cut into the ground.

Below.
....is the top of the foundation wall. Simple as that.
The top of a foundation at grade. Foundation walls should be a minimum of 8 inches ABOVE grade.
Full basement is the grade of concrete that is laid for foundation.
Elementary ballet is a grade in ballet, It ranges from Pre-primary, primary, grade 1 , Grade 2, Grade 3, Grade 4, Grade 5. They are the Junior years. Then it goes Pre-Elementary/Intermediate foundation, Elementary/Intermediate, Advanced Foundation, Advanced Foundation 1, Advanced Foundation 2. These are the senior years.

you cant, you have to put the foundation down first, then put the wall on top of the foundation (like around the edge of the foundation)
A grade C (if your in England)
Foundation can be a very dangerous job.
No you don't have to complete Grade 5 ballet to do Intermediate Foundation, you don't even have to be in Grade 5. Hope this helps!
In RAD, you start wearing pointe shoes in Intermediate Foundation.
