снега
"Снега" is the plural form of "snow" in Russian.
Here, 'снега' is in the genitive singular form, used to express an amount or quantity of snow.
Зимой много снега выпадает на землю.
In winter, a lot of snow falls on the ground.
'Снега' is again in the genitive singular form, describing the snow remaining after snowfall.
После сильного снегопада осталось много чистого снега.
After the heavy snowfall, a lot of clean snow remained.
Though 'снега' itself is not used, 'снегу' (dative case) is featured, showing how the base word 'снег' is declined based on context.
