Scratch Terminology

The following is a list of words that are used commonly by those who are participating with the development of the Scratch programming language, and whose meaning may not be clearly understood by those new to programming in Scratch. If there are additional words or terms that are used by the Scratch community that you may not understand, please simply add that word to this list without a definition. If you are an "old hand" to the Scratch community, help us out as well by adding words that may be confusing.
