Etymology

Origin of fingerprint

First recorded in 1855–60; finger + print

Explanation

The impression or mark that your finger makes on a surface is a fingerprint. And the one-of-a-kind pattern of raised whorls and lines on your fingertip? That's also a fingerprint. The earliest attempts to identify people using the prints their fingers made were in the 1820s, and by 1834 the word fingerprint came into use. To fingerprint someone is to press their finger into a pad of ink and then onto paper; after an arrest, the resulting fingerprints are put on file. The pattern on a person's fingertip is nearly unique, distinct, and won't change during their lifetime, making it a useful way to confirm someone's identity.
