Serif refers to a style of typeface characterized by small lines or decorative strokes that extend from the ends of the letters. These features can enhance readability and are often used in printed materials like books and newspapers. Common serif fonts include Times New Roman and Georgia. The use of serif fonts is prevalent in traditional publishing, as they are believed to guide the reader's eye along the lines of text. In contrast to Sans Serif fonts, which lack these embellishments, serif fonts convey a sense of formality and elegance, making them a popular choice for formal documents and literature.
