Serif font (serifs in red) |
A serif is a term in typography. If a letter is made of a line or lines, a serif is a tiny decorative line on the ends of letter's 'limbs'. Thus, in the illustration on the right, each serif letter has a serif on the end of its lines. Alphabetic typefaces either have serifs or not. Those without are called sans-serif.
The design of our typefaces started in the 15th century, when the early printers used moulds from which letters made of lead were produced.
However, the original source of the serif may be in monumental inscriptions. Serifs are on the letters at the base of Trajan's column (built 107~113 AD), and are clearly illustrated in standard textbooks on typography. Indeed, older literature often describes typefaces with serifs as Roman. The word serif seems to be an early 19th century innovation.
