What exactly does that mean? A pieced block? Sorry I am a newbie

There are unlimited number of pieced block patterns. Basicly they are made up of shapes (squares, triangles, etc) and put together. Then the blocks are sewn together to create a quilt. What are you looking at doing to jump into this madness called quilting? lol

Any block that is made up of other pieces of fabric - whether several squares or triangles or whatever.
Any block that is not just cut from one fabric.
