词汇 | germ |
词源 | germ. The Latin word germen, “sprout,” is the ultimate root of germ. Long before it meant the seed of a disease, a usage first recorded in 1803, germ meant “any portion of a living thing, animal or vegetable, that is capable of development into a like- ness of that from which it sprang.” Hence the name wheat germ for the tiny living protoplasm in the wheat kernel. |
