dwarf: [OE] Dwarf is descended via Germanic *dwergaz from Indo-European *dhwergwhos, which denoted ‘something tiny’. In English, it originally meant simply ‘person of abnormally small stature’; the modern connotation of ‘small manlike creature that lives underground and works metal’, a product of Germanic mythology, is not recorded until the late 18th century. The word’s German relative, zwerg, is the source of English quartz. => quartz[dwarf etymology, dwarf origin, 英语词源]
