Late Middle English: from Latin index, indic- 'forefinger, informer, sign', from in- 'towards' + a second element related to dicere 'say' or dicare 'make known'; compare with indicate. The original sense 'index finger' (with which one points), came to mean 'pointer' (late 16th century), and figuratively something that serves to point to a fact or conclusion; hence a list of topics in a book (‘pointing’ to their location).

  • In Latin index meant ‘forefinger, informer, sign’, Its second part is related to dicare ‘to make known’, also the source of indicate (early 17th century) and related words. The earliest uses in English refer to the finger that we would now usually call the index finger. Because this finger is used for pointing, index came to mean ‘a pointer’, either a physical one or some piece of knowledge that points to a fact or conclusion. And because a list of topics in a book points to their location in the text, publishers and scholars gave such a list the name index in the late 16th century.
