“Frangible” is an adjective describing delicate or breakable objects. It’s most useful describing a brittle texture that could snap or crumble in your hands. The Latin root of “frangible” is “frangere,” meaning “to break,” which is also the same root of the word “fragile.” While “fragile” is a synonym for “frangible” when it’s describing an object, “fragile” has a second usage for describing people. In this sense, a fragile person is “not strong or sturdy; delicate and vulnerable.”
