ddagger

Represents a double dagger symbol commonly used as a secondary footnote marker or reference indicator in academic writing.

Overview

Serves as a standardized citation and annotation mark in scholarly documents, particularly when multiple footnotes need distinct markers on the same page.

  • Typically appears as the third reference mark after asterisk (*) and dagger (†)
  • Common in mathematical proofs, academic papers, and technical documentation
  • Often used in conjunction with other footnote symbols in complex documents requiring multiple levels of annotation
  • Particularly useful in tables and equations where multiple references need clear visual distinction

Examples

Marking a second footnote reference in mathematical text when multiple footnotes are needed.

f(x)=ax2+bx+c‡f(x) = ax^2 + bx + c^\ddagger 
f(x) = ax^2 + bx + c^\ddagger

Indicating a double dagger reference mark in chemical equations or reactions.

2H2+O2→‡2H2O2H_2 + O_2 \xrightarrow{\ddagger} 2H_2O 
2H_2 + O_2 \xrightarrow{\ddagger} 2H_2O

Using double dagger as a superscript to denote a specific condition or state.

E‡=ΔG+RTln⁡(kBTh)E^\ddagger = \Delta G + RT\ln(\frac{k_BT}{h}) 
E^\ddagger = \Delta G + RT\ln(\frac{k_BT}{h})
