Etymology: Earthworm is about as transparent as compounds get: "earth" plus "worm," with the worm named for living in the ground. What makes it more interesting is how the name has held steady across the North Sea. Its cousins in Dutch (aardworm), West Frisian (ierdwjirm), and Saterland Frisian (Äidwurm) all follow the same pattern, which suggests the compound was an ordinary descriptive naming choice shared by the early Germanic-speaking communities of the region. In English, the compound took shape in Middle English, where forms such as "erthe-worm" and "erþe worm" appeared. Earlier writers also used phrases like "worm of þe erthe," so the modern single word was a later tidying-up of a longer descriptive phrase. The name simply told speakers where to find the creature, which is why the same logic appears in several neighbouring languages.
