Immaculate means spotless, pure, and clean as fresh snow on a far-off mountain. Only obsessive cleaners can keep immaculate homes, but it’s a goal we can strive for, like that far-off mountain.
Immaculate literally means without a spot or a stain. We can use immaculate to describe physical things, like bathrooms or kitchens. But we also use the word metaphorically to describe honor or purity, like the “immaculate conception,” when Mary got pregnant with Jesus without losing her virginity. Or someone with a pure, exact singing voice could be described as having immaculate pitch. If your home team plays a perfect game, you could say their performance was immaculate.
