SAHIB, a title of respect in India, specially used to designate Europeans. The word is Arabic, and originally means a companion. It is generically fixed to the titles of men of rank, as Khan Sahib, Nawab Sahib, Raja Sahib, and is equivalent to master. The proper feminine form is sahiba; but the hybrid term memsahib (from madam and sahib) is universally used in India for European ladies.
