Word Origin & History

index 
1398, "the forefinger," from L. index (gen. indicis) "forefinger, pointer, sign, list," lit. "anything which points out," from indicare "point out" (see indicate). Meaning "list of a book's contents" is first attested 1580, from L. phrases such as Index Nominum "Index of Names," index expurgatorius "specification of passages to be deleted from works otherwise permitted." The verb meaning "compile an index" is from 1720. Scientific sense (refractive index, etc.) is from 1829; economic sense (cost-of-living index, etc.) is after 1886. The Church sense of "forbidden books" is from index librorum prohibitorum, first published 1564 by authority of Pius IV.

index of refraction  
A measure of the extent to which a substance slows down light waves passing through it. The index of refraction of a substance is equal to the ratio of the velocity of light in a vacuum to its speed in that substance. Its value determines the extent to which light is refracted when entering or leaving the substance.
