| script | the name for a piece of code in Scratch that responds to some event. |

| costume | a graphic associated with a sprite. A sprite can have several of these, only one of which is displayed at a time. |
| bug | when a program doesn't work the way it should. It might cause the program to completely stop working, or it may cause the program to do something, just not the right thing. |
