quotidian

A quotidian commute sounds grander than it feels: the word began with a Latin question about counting—quotus, “how many?”—and attached itself to dies, “day.” Latin speakers used the resulting expression for something that happened every single day, a useful label for recurring fevers in an age when medicine was largely guesswork and pulse-taking. By the mid-fourteenth century, English had borrowed it through French as coitidian, before its spelling acquired the more familiar qu in the sixteenth century. The word then made a small semantic journey from “daily” to “ordinary,” as if repetition itself slowly sanded the glamour off an event. So when you call a train ride quotidian, you are quietly carrying an ancient Roman calendar—and the memory of a daily fever—into the morning rush.
