Why “nilas” is a great word
A smooth, elastic sheet of sea ice, less than ten centimeters thick, that forms a new skin on the ocean's surface. From Russian ни́лас (nílas), from Saami nulas, meaning 'stripe'; first attested in English in 1960. Unlike pancake ice, a slurry of jostling discs with turned-up edges, or fast ice, a rigid, anchored immobility, nilas is a continuous, fragile membrane, freely floating on the brine from which it is born. It is the dark, glassy skin that dims the water's swell, bends without breaking under a seabird's weight, and fractures with a soft, high ring like a struck wineglass—the provisional peace, a stripe of frozen possibility, before the chaotic consolidation of the frozen world.
