Etymology: "Chronometric" is a straightforward formation: it joins "chrono-", from Ancient Greek "khrónos" meaning time, with "-metric", from "métron" meaning measure. The pattern follows "chronometer," the older instrument name, so the adjective describes anything relating to measuring time precisely, from clocks to radiocarbon dating methods. The building blocks are much older than the English word. "Khrónos" and "métron" were everyday Greek nouns long before anyone combined them, and the English "-metric" ending mirrors many other scientific adjectives such as "geometric" and "photometric." Once "chronometer" existed as a name for a precise timekeeping device, "chronometric" followed naturally as its adjective, and scientists later extended it to methods that estimate elapsed time, such as dating techniques in archaeology and geology.
