Because of this derivation, chimera and its adjective, chimerical, came to mean something illusory, fantastical, hoped-for but impossible. Then scientists learned to make the illusory real, which changed the nature of the word. Gardeners have been grafting twigs from one kind of plant onto stems of another since classical antiquity. Eighteenth-century biologists created chimerical invertebrates using hydras and worms. Medical chimerism now refers primarily to organ transplantation, which establishes two genetically different cellular lineages within the transplant recipient. If, after a bone marrow transplant, the new blood-forming system is genetically the donor's, the recipient is a chimera. But so are mermaids and unicorns. — JSConversational, opinionated, and idiomatic, these Word Notes are an opportunity to see a working writer's perspective on a particular word or usage. |
