Etymology: "Aridities" is the plural of "aridity," a noun for extreme dryness. The base word, "arid," comes from Latin "aridus," meaning dry or parched, which derives from the verb "arere," to be dry. English took the noun directly from Latin "āriditās," meaning dryness, so the modern form is a straightforward borrowing rather than something that passed through French first. The construction is simple: "arid" plus the suffix "-ity," which turns an adjective into a noun of state or quality, as in "vanity" or "humidity." Its Latin ancestor "āriditās" was built the same way, from "āridus" and the suffix "-itās." The plural "aridities" follows the ordinary English pattern of changing the final "y" to "ies," and it is used when speaking of several distinct dry conditions or regions at once.
