NAWAB  , a

Mahommedan title for a native ruler in India, answering to the Hindu raja . Nawab originally means a deputy, being the honorific plural of the Arabic naib, and it was applied to a delegate of a supreme chief, the viceroy or governor under the Great Mogul, e.g. the nawab of Oudh . From this use it became a title of rank, without office, and is now sometimes conferred by the British government on Mahommedan gentlemen for distinguished service .
