Definition

The ampheck is either one of the symbols devised by Charles Sanders Peirce to denote the logical connectives:

Logical Nor: $p \curlywedge q$: $p$ nor $q$
Logical Nand: $p \mathrel{\bar \curlywedge} q$: $p$ nand $q$


Linguistic Note

The word ampheck comes from the Greek $\alpha \mu \phi \eta \kappa \eta \varsigma$ meaning double-edged.
