Etymology: The word is a plural, so the core story is in its singular, "absorptiometer," which is a technical coinage built from two inherited pieces. "Absorption" comes from Latin "absorbere," meaning to suck up or swallow, formed from "ab" (away) and "sorbere" (to suck in). The "-meter" ending comes from Ancient Greek "métron," meaning measure, which passed into French as "mètre" and then into English as "-meter." The "-o-" linking the two parts follows the classical pattern of joining Greek and Latin elements in scientific compounds. Put together, an absorptiometer is an instrument for measuring how much of something a material or substance takes in. The plural simply counts several such instruments, and the whole word was assembled in modern scientific English from classical building blocks rather than being handed down from antiquity. Ancient Greeks and Romans had no devices by this name, and the word is a product of the modern laboratory era.
