water's chill alter ego, lighter than its liquid self and stubbornly slow to melt
means Frozen water, solid and cold, found as cubes in drinks, sheets on ponds, or caps on the poles.
from From Old English 'is,' a word for frozen water that has cousins all across the Germanic family — German 'Eis,' Dutch 'ijs,' Old Norse 'iss.' These all trace back to a Proto-Germanic '*isaz,' with possible deeper relatives in Avestan and other Indo-European tongues. The word has stayed remarkably short and sharp for millennia, much like the thing it names.
