The Latin word from which it's derived means "unmarried." In normal present-day English it means refraining from sex. I enjoy etymologies, but they do not determine current meanings, else, for example, we wouldn't be able to use the word "arrive" unless we meant by boat or swimming, since it means "to reach shore," and we wouldn't use the word "dreary," except as it is used in Beowulf to describe the bloody mess left by Grendel.
