The double dagger (‡), also known as a diesis, is a classic typographic symbol traditionally used to indicate the third footnote on a page, following the asterisk and single dagger. Beyond standard publishing, it frequently appears in chemistry to denote a chemical reaction's transition state or in historical texts to mark a year of death. While rarely seen in casual texting, it remains a staple in academic formatting and detailed technical documentation.
