The English adjective free is commonly used in one of two meanings: "at no monetary cost" (gratis) and "with little or no restriction" (libre). This ambiguity of free can cause issues where the distinction is important, as it often is in dealing with laws concerning the use of information, such as copyright and patents. Richard Stallman summarised the difference in a slogan: "Think free as in free speech, not free beer."
