Why was "tantrum" trending last week?
late 14c., "self-restraining," from Old French continent and directly from Latin continentem (nominative continens) "holding together, continuous," present participle of continere "hold together" (see contain). Meaning moved from "exercising self-restraint" to "chaste" 14c., and to bowel and bladder control 19c.
"large land mass," 1550s, from continent land (mid-15c.), translating Latin terra continens "continuous land," from continens, present participle of continere (see continent (adj.)).
Note: Continents are made from the lightest rocks in the Earth. Some of these are also the oldest known rocks on Earth, with an age of 3.5 billion years, measured by radioactive dating.
Note: According to the theory of plate tectonics, continents move along piggy-back on the tectonic plates like rafts floating on water.
