The pilcrow, also called the paragraph mark, paragraph sign, paraph, alinea (Latin: a lineā, "off the line"), or blind P, is a typographical character for individual paragraphs.
The pilcrow can be used as an indent for separate paragraphs or to designate a new paragraph in one long piece of copy, as Eric Gill did in his 1930s book, An Essay on Typography. The pilcrow was used in the Middle Ages to mark a new train of thought, before the convention of physically discrete paragraphs was commonplace.
The pilcrow is usually drawn similar to a lowercase q reaching from descender to ascender height; the loop can be filled or unfilled. It may also be drawn with the bowl stretching further downwards, resembling a backwards D; this is more often seen in older printing.
