In typography and handwriting, a descender is the portion of a grapheme that extends below the baseline of a font.
[1] The parts of characters that extend above the x-height of a font are called ascenders.
[2] Descenders are often reduced in small-print typefaces for uses such as newspapers, directories or pocket Bibles to fit more text on a page.
Contemporary systems that did not have this restriction were described as supporting true descenders.
Some type designers have observed the “tails” of some Thai glyphs to be analogues to the descenders.
