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.
