Used of a path, drive, or road that has a surface made of gravel — those small loose stones — instead of grass, dirt, or smooth tarmac. You walk on a gravelled path and hear the crunch. It is the -ed form of gravel, used like an adjective: a gravelled courtyard, a gravelled drive. British English writes gravelled with two l’s; American English usually writes graveled with one. Though actually, in older British books you may also meet I was gravelled, meaning someone was stuck and did not know what to say. That use is uncommon now. The meaning you will meet in ordinary life is the path or road.
