To move a thing by pulling it along a surface. Also resistance against motion — the same word for the act and what opposes it.
Old English dragan, or a cognate Old Norse form, to pull or draw along a surface; the same root gives both the pulling motion and the resistance that opposes it.
The moving of a thing by pulling it along, or the resistance that answers any motion. The same word names an act and what pushes back against it.
