A Tautonym or reduplication is a word or name consisting of two identical parts, one following the other - a term such as OO, KAKA, ELEELE, RAHURAHU, XIQUE-XIQUE, TANGANTANGAN, OR KANDIRI-KANDIRI. The latter, by the way, is a musical bow of the Balese of the Congo, with the tuning loop but no resonator (Sibyl Marcuse, Musical Instruments: A Comprehensive Dictionary, Garden City, New York, Doubleday & Company, Inc., 1964). The term REDUPLICATION is just as redundant as tautonyms give the impression of being, for its meaning adds exactly nothing to that of the simpler word DUPLICATION.
