The word "version" means a new and slightly different copy of something that already exists. For example, if you write an essay, print it, then make changes to it and print it again, you have two versions of the essay.
But this word is a little tricky because if you just change one word of the essay, it probably wouldn't be considered a different version from before. There are different times that we could call it a new version, depending on the situation:
- When you save the changes you made, that could be considered a new version.
- When you print out a new copy with changes on it, that can be called a new version.
- When you submit the document with changes made to it, that's also a new version.
