@justvanrossum @Sveinbjorn @eWalthert @letterror @MauriceMeilleur @jeremiehornus @glyphs My friend Claude de Antropic says: There is another singular form, "matrice," derived from the Latin word "matrix" and used in some specific contexts in English. In printmaking and sculpture, a "matrice" is a mold or a die used to create a relief or intaglio print, or to cast a sculpture. "Matrice" keeps the connection to the historical use in font casting and typesetting but is distinct from "matrix".
