The season of the year when it is cold and often snowy, usually from December to February in the Northern Hemisphere.
From Old English 'winter' (season of cold and snow) combined with 'time' (period). 'Winter' itself comes from Germanic roots and may relate to 'wet' or 'wind.' The compound is straightforward—literally 'the time of winter.'
Your body actually responds differently to wintertime—seasonal affective disorder (SAD) affects many people because shorter days reduce serotonin production, which is why some cultures developed traditions like Christmas lights to combat winter darkness.
