tenten 点々

In Japanese, tenten 点々 means "dots" or "points." It's a reduplication of ten 点, which means a "dot" or "point."

The word is sometimes used to refer to symbols that look like dots, such as dakuten 濁点 (゛) and the ditto mark (〃), which are also called chonchon ちょんちょん, *striking repeatedly* (phenomime), due to how your hand moves in order to write them.
