Etymology

Origin of convertible

First recorded in 1350–1400; Middle English word from Medieval Latin word convertibilis. See convert ¹, -ible

Explanation

If it starts to rain while you’re riding in a convertible car with the top down, you can always put the top back up. Convertible is an adjective that means “capable of changing from one form to another.” Something that is convertible can be changed or transformed from one thing to another. Money, for instance, is convertible because it can be changed from one currency to another — for example, from dollars to euros. A sofa bed is convertible because it can be transformed from a sofa into a bed. Likewise, a convertible jacket is a jacket that can be changed (by removing the sleeves or an inner lining) depending on the weather.
