Etymology: "Aneurismal" is simply the adjective form of "aneurism," with the suffix "-al" (meaning "relating to") attached to that noun. It describes things relating to an aneurism, the abnormal swelling or ballooning of a blood vessel wall, which is why the term sits naturally in medical descriptions of arteries and their walls. The noun it builds on, "aneurism," comes from the Greek "aneurysma," formed from "ana" (meaning "up" or "through") and "eurys" (meaning "wide" or "broad"), a sense that points to something widened or dilated. The English spelling "aneurism" is the older form, and "aneurysm" is a later variant that has become common in modern medical writing, so the adjective has two spellings in use alongside each other.
