The word "Dada" may be an allusion to an infant's first words, such as "Mama". No-one knows who invented the name, but there is some historical evidence which says that Tzara picked it out at random from a German-French dictionary, since "Dada" means "hobbyhorse" in French. A hobbyhorse is a long stick with a toy horse head attached which a child can hold in front of them to pretend they are riding a horse. Still, the source of the name is not widely agreed upon.
