I'm 12 and this is for my Technology homework to explain what it is in your own words. I keep looking on the internet but I can never understand big words like it. Can someone please explain in english I understand? Oh and can you name one other joint and I'll find out what it means.

"A lap joint is one of the many joints used to join two pieces of wood together. With a lap joint, this is done by overlapping the wood and fastening them together." "The finger joint (also known as a comb joint) is a woodworking joint made by cutting a set of complementary rectangular cuts in two pieces of wood, which are then glued. To visualize a finger joint simply interlock the fingers of your hands at a ninety degree angle; hence the name "finger joint." It is stronger than a butt or lap joint, and often forms part of the overall look of the piece.

The finger joint is the most common joint used to form long pieces of lumber from solid boards; the result is finger-jointed lumber."
