noce

from Vulgar Latin noptiae, an altered form of the classical nuptiae ('marriage, wedding, carnal commerce, coupling'), itself derived from nupta, the feminine past participle of nubere, 'to veil,' as the Roman tradition required women to take the veil to marry. See nubile and nuptial, which are derived from it. nubes, 'cloud' in Latin, is another representative of this Indo-European root and gave rise to nubilare and obnubilare, 'to cover with a cloud,' from which the French obnubiler comes. As for the shift from nuptiae to noptiae, it is due to the influence of novius, 'newlywed' in Vulgar Latin (from novus, 'new').
