Domestic means to do with the home, or with a country's own affairs. Domestic chores, domestic flights, domestic policy.
The two senses are far apart and both are everywhere: a domestic flight stays inside one country, and domestic work happens in a house. Domestic abuse is violence within a household, and it is a criminal matter. The Latin domus means a house.
