Why this word is great
FERIAL — [Adjective] Pertaining to an ordinary weekday, or conversely, to something jovial and festive as if it were a holiday. From Middle English ferial, from Medieval Latin fēriālis, rooted in Latin fēria ("weekday") and fēriae ("holidays"), it is a word of dual allegiance—both to the unremarkable and the celebratory. Unlike "festal" (which specifically denotes celebration) or "mundane" (which implies dullness), ferial occupies the liminal space between obligation and revelry. It is the quiet hum of a Tuesday morning, the unexpected lightness of a workday picnic, or the way sunlight slants through an office window with the same golden hue as a holiday dawn—a reminder that the ordinary and the extraordinary are often the same thing, seen from different angles.
