The ascenders are the parts of the characters that lie above the midline.
In
typography, an 'ascender' is the portion of a
letter in a Latin-derived alphabet that extends above the
mean line of a
font. That is, the part of the letter that is taller than the font's
x-height.
Ascenders, together with
descenders, increase the recognizability of words. For this reason, British highway road signs that must be read quickly no longer use all
capital letters.
