Sanitary and hygienic apply to physical well-being as promoted by the eradication of the causes for sickness, disease, or the like; sanitary, however, is used of measures and conditions affecting people in general, whereas hygienic connects itself with personal habits.

Several hybrid derivations have been suggested, none of them probable, and I lean to the suggestion that the starting-point of the word may have been "jumkhana", a term which, though it is not in Forbes's Hindustani Dictionary, I have heard a native apply to a large cotton carpet, such as native acrobats, or wrestlers, might spread when about to give a performance.
