"Umbra" means shadow and "pen" means almost. Think of a wide light source, like a TV screen in a dark room; if you hold up a book so that it blocks out that screen, you're (your face and eyes, at least) in the book's umbra. If you hold it so you can see PART of the lighted screen, you're in the penumbra.
Now substitute the Sun for the TV and the Moon for the book. You see a total solar eclipse from umbra and a partial eclipse from the penumbra.
