- Fundamental idea: Free as in beer
In a nutshell, the word "free" has a couple of meanings and it's not always possible to tell in context which one the user meant. "Free as in beer" refers to the cost (i.e. money) of the software, while "free as in speech" refers to what you are allowed to do with the software.
