Etymology: Ancient Greek "anodynos" was built from "an-", meaning "without", and "odyne", meaning "pain" or "grief," so its literal sense is "painless" or "without pain." Greek physicians used the related "anodyne" for remedies that relieved pain, and the word carried that medical sense into English. Its figurative use, "not offensive" or "harmless," developed later, and English writers came to apply it to speech and entertainment that could not give anyone cause for complaint. The word reached English in the 1600s, borrowed from Late Latin "anodynus," which was itself taken from the Greek. Its earliest English uses were medical, describing drugs and treatments that dulled suffering, and this sense remains the main one today. The figurative sense of "inoffensive" came only afterward, so a word that began as a term for painkillers ended up describing dull, safe conversation.
