    Definition of Colon

    A colon (:) is a punctuation mark used to introduce and highlight information that follows it. It is commonly employed to introduce lists, explanations, quotations, or examples that elaborate on the preceding clause. In addition to providing clarity and emphasis, a colon connects the preceding statement to the subsequent content, ensuring that the latter expands or clarifies the former. Proper use of a colon enhances the readability of text by signaling to the reader that additional, related information is forthcoming. For instance, in a sentence like “He had one goal: success,” the colon indicates that the word “success” is directly explaining or defining the goal mentioned earlier.
