what is Serif in typography

Serif refers to the small decorative strokes or lines that extend from the ends of the main strokes in a letter or symbol. These are often found in traditional typefaces, such as Times New Roman, Garamond, or Baskerville. Serif typefaces are generally considered to be more formal, traditional, and old-fashioned, and are commonly used for printed material such as books, newspapers, and magazines. The presence of serifs is believed to aid in legibility and flow of reading text in print.
