Gratis versus libre is the distinction between two meanings of the English adjective "free"; namely, "for zero price" (gratis) and "with few or no restrictions" (libre). The 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.
