penumbra
The Latin word "umbra" means "shadow". The prefix "pen-" means "almost" or "partly", so "penumbra" means a partial shadow.

partial of u with respect to x = partial of v with respect to y partial of u with respect to y = -1*partial of v with respect to x

Penumbra
Not precisely. The umbra is the TOTAL part of the shadow. In a total eclipse, where the eclipsing object is spherical, then the "inner" part of the shadow is the umbra, but in a partial eclipse, there IS NO umbra; just the "penumbra", the partial shadow.
The darker total shadow is called the "umbra"; the lighter, partial shadow is called the "penumbra".
The darker complete shadow is the "umbra". The lighter partial shadow is the penumbra.
The umbra is the darker total shadow; the penumbra is the surrounding partial shadow.
The darkest, "total" shadow is called the "umbra", while the partial shadow is called the "penumbra", from the latin prefix "pen" meaning "almost".
A Solar Eclipse, depending where you are in relation to the shadow, depends on whether you see a total Eclipse or a partial.
Complete shade hides the shadow and makes it non visible. Partial shade allows the shadow to be visible.
It first enters the penumbral shadow, or outer shadow caused by the Sun shining "around" the Earth. For a "partial" lunar eclipse, the Moon eventually but only partly enters the dark red "umbral shadow." If it doesn't, the eclipse is called a penumbral eclipse.
No, the umbra is the darkest part, the area of maximum eclipse (which moves as the Earth turns).The area of partial eclipse is called the penumbra.
