see the dark side of the moon

== English == === Etymology === The "far side of the moon", the side we don't see from home, is sometimes referred to colloquially as the "dark side of the moon" where "dark" means "unseen" rather than "unlit." In the latter sense, there is no dark side, as both sides of the moon receive equal sunlight. This makes it more or less impossible to see the "dark" side of the moon if this is taken to mean "unlit", and it is impossible to see the "far" side of the moon from Earth in the sense of "unseen." === Verb === see the dark side of the moon (third-person singular simple present sees the dark side of the moon, present participle seeing the dark side of the moon, simple past and past participle saw the dark side of the moon) (idiomatic) To do or experience something exceedingly difficult or rare.
