英语词汇yo-yo的起源、历史背景-英语词源词典

yo-yo. Yo-yo, for the child’s toy that spins up and down on a string, was once a trademark. In 1929 a Chicago toymaker patented the toy and was granted the trademark Yo-Yo. The manufacturer had noticed a Filipino youth playing with such a toy on the streets of San Francisco and purchased it from him. In his application for the trademark he claimed that he had coined the word Yo-Yo after noticing that children often shout “You! You!” to each other when playing some games. All he had done was to strike the u from these words, he ex- plained. In any case, the novelty sold millions, until a com- petitor marketed the same product under the same name. The Chicago manufacturer quickly brought suit for infringe- ment of his trademark, but after hearing the evidence the court ruled against him. It seems that his competitor offered incontrovertible proof that he had been raised in the Philip- pines and as a boy had often played with a toy called a yo-yo. There was no doubt that the toy was of ancient Oriental ori- gin and that it was long called by the Philippine name yo-yo. The court ruled that the trademark should never have been issued and today any manufacturer can use the term yo-yo.
