pilcrow (¶)
Definition - The name of the ¶ symbol. It is used:
(1) to designate a new paragraph,
(2) in word processors to visually indicate where the paragraph unit ends, and
(3) in proofreading to show that a paragraph should be split into multiple paragraphs.

Etymology -
According to the OED, it perhaps originated as the word pylcraft, which was a corrupted form of the word paragraph; however, "the history of the word is obscure, and evidence is wanting."

Oxford English Dictionary -
The word's first citation is from circa 1440: "Pylcrafte, yn a booke … asteriscus, paragraphus."
(Promp. Parv. 398/1)
