Grammar hook - bare instrumental for seasons

To say "in winter" or "in summer," Russian uses the instrumental case without any preposition:

зимой - in winter весной - in spring
летом - in summer осенью - in autumn

This is the only time Russian uses bare instrumental to mean "in/during." Everywhere else, instrumental needs a preposition like с (with). Notice how each ending reflects the noun's gender: -ой for feminine (зима, весна), -ом for neuter (лето), and -ью for soft-sign feminine (осень).

Cultural context

Русская зима is a cultural concept. Winter dominates Russian identity and language. "Русская зима" (Russian winter) isn't just weather - it's the force that defeated Napoleon and the Wehrmacht. It shapes architecture, food preservation, holidays, and the national character. When Russians say "у нас зима длинная" (our winter is long), they mean it as identity, not complaint.

Дача culture defines лето. For millions of Russians, summer means the дача - a country house with a garden. "Летом мы на даче" (in summer we're at the dacha) is the default answer. Growing vegetables, picking berries, and grilling шашлыки is how Russian summer is spent.

Осень has a special place in literature. Pushkin famously loved autumn and wrote some of his best work during "Болдинская осень" (Boldino Autumn). Russians associate осень with melancholy beauty - golden leaves, rain, and the bittersweet end of warmth.
