U+2021 "‡" Double Dagger Unicode Character

Unicode Version 17.0

U+2021 "‡" Double Dagger is a typographic symbol that follows the single dagger (†) in historical and modern usage, primarily serving as a reference mark in written texts to indicate a footnote or endnote, especially when a third tier of notation is needed after the asterisk and the dagger have already been used. It also has specialized functions in other fields, such as linguistics where it sometimes marks an extinct or reconstructed language form, and in biology to denote a dead specimen. In medieval manuscripts and early printed books, it was also employed as a secondary obelisk to draw attention to notable passages or corrections, though its use has diminished with the rise of superscript numbering systems.
