Etymology: Oilpaper is about as transparent a compound as English offers: it is simply oil combined with paper, the oil being what makes the sheet waterproof and translucent. The oil soaks into the paper's fibres and fills the tiny gaps between them, so light passes through more easily and water is repelled. That plain logic is what the word records, with no borrowed roots or hidden detours to unpick. The practical result is a material used for wrapping and protection, where a plain wrapper would soak through or tear. Because the compound is built from two ordinary English nouns, its meaning can be read straight from its parts, which is why it has changed so little from its original sense.
