Duocontrachotomy
Dichotomy following the (x/not x) formula, employing a word that can signify itself and the opposite of itself at the same time as part of the binary
The duocontrachotomy (sanctioned/not sanctioned) is a true dichotomy, and the word "sanction" can signify both "endorsed" and "punished", meaning the one expression covers both "wholes" of a dichotomy at the same time, while having them as opposites internally and externally in regards to the expression itself
