Possessable and Unpossessable
Many languages, such as the Maasai language, distinguish between the possessable and the unpossessable. Possessable things include farm animals, tools, houses, family members and money, while for instance wild animals, landscape features and weather phenomena cannot be possessed. Basically this means that, in such languages, saying 'my brother' is okay, but 'my land' would be grammatically incorrect. Instead, one would have to use a circumlocution such as 'the land that I own'.
