de·base
/dɪˈbeɪs/ verb · debased; debasing; debases
From de- “down” + base “low, of little worth” — as in a base metal, the opposite of a noble one. The word has spent six hundred years meaning to make something worse while pretending otherwise. Four of its five senses describe things this token cannot do. The fifth is the oldest, and it is the only instruction the contract takes.
