The term 'Parts of Colons' refers to the two main components of a colon, which are the DOTS and the segment. The DOTS, also known as the punctuation mark, are used to indicate a pause or separation in a sentence. The segment is the part of the colon that follows the DOTS and is used to introduce a list, explanation, or quotation. Together, these two parts of a colon help to create a more organized and structured sentence.
