What does ‡ mean?
The double dagger (‡), also known as the diesis or double obelisk, is a specialized reference punctuation mark distinguished by its two horizontal crossbars. In traditional editorial footnoting without numbers, the double dagger serves as the third mark on a page, directly following the primary asterisk (*) and the single dagger symbol (†). If additional notes follow on the same page, the sequence continues with the section sign (§) and the pilcrow.
In physical chemistry and chemical kinetics, the double dagger denotes a chemical transition state or activated complex (e.g. ΔG‡ for activation Gibbs free energy). Typographers also use it in statistical data tables to signify third-tier confidence thresholds (such as p < 0.001). Browse related reference marks in reference mark and explore classical punctuation symbols.
Common uses
- Tertiary footnote indicator directly following the asterisk (*) and single dagger (†)
- Physical chemistry marking transition states and activation parameters: “ΔH‡”
- Statistical reporting tables indicating third-level significance values
