Ellipsis dots refer to the three dots that are used to indicate the omission of words in a sentence or passage. They are also known as suspension points, dot-dot-dot, three dots, and dot-dot-dot triangle. Some people refer to them as an ellipsis mark, but technically the term ellipsis refers to the omission itself rather than the punctuation used to indicate it. Other variations of ellipsis dots include the double-dot ellipsis, which consists of six dots arranged in two sets of three, and the four-dot ellipsis, which includes a period at the end of the sentence in addition to the three dots. Regardless of the terminology used, ellipsis dots are an important punctuation mark in written communication.
