The Earth's shadow has two parts:
Umbra - dark inner shadow. Total lunar eclipses occur when the entire Moon passes through the umbral shadow. Partial lunar eclipses occur when only a portion of the Moon passes through the umbral shadow.
Penumbra - faint outer shadow. Penumbral lunar eclipses occur when the Moon passes through the penumbral shadow but are very difficult to observer so are of internest mainly to astonomers.
