Word Root of DOMAIN

The Latin word dominus, meaning master, gives us the root domin. Words from the Latin dominus have something to do with being another's master. To dominate is to have power and control over as if being someone's master. A domain, or land under the control of a government, is a land with a particular master or ruler. Dominion is controlling power, similar to the power of a master over others.
