  • In typography, a glyph that resembles a capital C crossed by one or two vertical lines.

    "Like most punctuation, the paragraph mark (or pilcrow) has an exotic history. It's tempting to recognize the symbol as a 'P for paragraph,' though the resemblance is incidental: in its original form, the mark was an open C crossed by a vertical line or two, a scribal abbreviation for capitulum, the Latin word for 'chapter.' Because written forms evolve through haste, the strokes through the C gradually came to descend further and further, its overall shape ultimately coming to resemble the modern "reverse P" by the beginning of the Renaissance. Early liturgical works, in imitation of written manuscripts, favored the traditional C-shaped capitulum; many modern bibles still do." —Jonathan Hoefler,
