The umbra is the darker total shadow; the penumbra is the surrounding partial shadow.
The word "umbra" comes from Latin, meaning "shadow." "Penumbra" is also from Latin, combining "paene," meaning "almost," with "umbra." "Antumbra" derives from Latin "anti," meaning "against," and "umbra."
Shadows have two parts, the umbra and the penumbra. The umbra is the darker part of the shadow, in which all of the light from the source is blocked by the object casting the shadow. The penumbra, also known as the half-shadow, is the grayish part along the edge of a shadow in which only some of the light from the source is blocked.During a solar eclipse, if you are within the umbra of the moon's shadow, you are witnessing a total eclipse, and if you are within the penumbra of the moon's shadow, you are witnessing a partial eclipse.
During the eclipse, the penumbra is the outer part of the shadow where only partial sunlight is blocked.
A solar eclipse happens when the Moon casts two shadows on Earth: the umbra, which is the darkest part of the Moon's shadow, and the penumbra, which is the lighter part. The umbra creates a total eclipse where the Sun is completely blocked, while the penumbra creates a partial eclipse where only part of the Sun is blocked.

umbra and penumbra
Umbra and penumbra when referred to the moon describes the shadow which is formed when light is blocked from the sun, by the moon. This shadow which falls on the Earth and has two distinct regions; a partially shadowed area which is the penumbra and the centre point a totally dark umbra. We on Earth looking skyward and watching the shadow pass as the Earth revolves would describe the penumbra as a partial eclipse and the umbra as a total eclipse.
During the eclipse, the penumbra is the outer part of the shadow where only partial sunlight is blocked.
