"Recent geological studies and limited geophysical measurements in this region have been cited to argue that uplift is due to internal imbricate 'stacking' of Asian crust…." -Professor James Ni as quoted by Donyelle Kesler in Las Cruces Sun-News (New Mexico), July 22, 2011 Did you know? The ancient Romans knew how to keep the interior of their villas dry when it rained. They covered their roofs with overlapping curved tiles so the "imber" (Latin for "pelting rain" or "rain shower") couldn't seep in. The tiles were, in effect, "rain tiles," so the Romans called them "imbrices" (singular "imbrex"). The verb for installing the tiles was "imbricare," and English speakers used its past participle-"imbricatus"-to create "imbricate," which was first used as an adjective meaning "overlapping (like roof tiles)" and later became a verb meaning "to overlap." These days, the adjective is usually encountered in scientific contexts. See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
