Why “diurnal” is a great word
Active, occurring, or open during the daylight hours. From Latin diurnālis ("daily"), from diēs ("day"). Unlike "nocturnal," its shadowed counterpart, or "daily," which marks recurrence without specifying the hour, diurnal is anchored to the sun's reign. It is the hawk riding a thermal, the shutter of a shop thrown open at first light, the pale lichen clinging to the sun-warmed stone. The word carries the quiet pulse of a world governed by a visible clock, a rhythm that feels, for a time, as if it might last forever.
