A solid wood door is what all doors were 100 years ago--solid wood.
Most interior doors today have a hollow core. They are made with a
narrow perimiter of solid wood and solid wood in the area of the handle
and lock. They are finished with a thin layer of veneer for the
If the door is smooth on both sides, it is called a slab door.
You can get slab doors as either solid or hollow core. Sold core
doors can be made from particle board with wood stiles around the
perimeter and veneer skins on both faces. The stiles can be pine
or hardwood to match the veneer. Solid doors can also be stave
core doors. Instead of the particle board, the inner filler is
random sticks of mixed woods. Fire doors are filled with a gypsum
or cementitious core. Hollow core doors are filled with a lattice
of cardboard or very thin wood slats.
Solid core doors are certainly not sold chunks of oak or birch.
Raised panel doors, on the other hand, can be solid real wood.

Yes. And it is solid, but not necessarily one thick piece. It may be
laminated, some cheaper wood inside, nice wood outside, but it is solid all
the way through. These are more secure for entry doors, heavier, more
Hollow core doors are a frame of wood and just covered with a sheet of
thinner wood on each side.
Solid = no air spaces. From front to back, you get wood.
Not Solid = a frame with wood veneer on each side. It's hollow.
Not Solid also is cheaper and used, mostly, for interior doors. Solid doors
are sturdier and stronger (and much heavier) and are used (mostly) for door
that open to the outside.
A compromise is a steel-clad door. It's hollow, but the facings of steel are
hardier than the wood veneer.
