Excludable means good for which it is possible to prevent consumers who have not paid for it from having access to it. Rival goods are whose consumption by one consumer prevents simultaneous consumption by other consumers. Non rival goods are those goods, if more than one person can consume the same unit of the good at the same time. (A good that is both excludable and rival in consumption is a private good.)
