Etymology: The surprising thing about "dull" is that its oldest sense was not about lack of shine or wit at all. In Old English, "dol" meant "foolish, erring, heretical" and even "presumptuous," so a dull person was once a silly or misguided one, not a boring one. The sense of being stupid or slow to understand survived for centuries alongside the physical sense of being blunt or lacking brightness, and the modern "not sharp or bright" meaning grew out of those earlier ideas. The deeper roots point to a notion of being stunned or bewildered. Old English "dol" comes from a Proto-Germanic form meaning "stunned, mad, foolish, misled," which in turn is linked to an ancient root meaning "to dim, cloud, make obscure." The same family of words turns up across the Germanic languages with meanings ranging from "mad" in Dutch and German to "deaf" and "slow to understand" in Scots, so the idea of a mind or senses clouded over runs through the whole group.
