Other forms: putties; puttied; puttying
Putty is the clay-like substance you can use to fill holes in a wall before painting it, or to secure a piece of glass in a window frame.
Putty comes in different colors and consistencies, but it's generally a very soft doughy material that can fit it small or awkward spaces and hardens after a certain amount of time. Before painting a wall, you might want to putty any holes or cracks, using a putty knife. After the putty dries, you can sand it smooth. The word comes from the French potée, "polishing powder."
