Questions & Answers about Летом мы часто ездим на дачу.

Why is летом in this form? Why not в лето or в летом?

Летом is the instrumental case of лето and here it means in summer / during the summer.

Russian often uses the instrumental case without a preposition for seasons and some time expressions:

• зимой = in winter
• весной = in spring
• летом = in summer
• осенью = in autumn

So Летом мы часто ездим на дачу is the normal way to say In summer, we often go to the dacha.

You can say в лето in some special contexts, but not for the ordinary meaning in summer.

What is the difference between ездим and едем?

This is a very common Russian question because it involves verbs of motion.

• ехать / ехать → едем = going right now, in one direction, usually as a single trip
• ездить → ездим = going regularly, repeatedly, habitually, or in different directions

In this sentence, часто (often) shows a repeated action, so Russian uses ездим, not едем.

• Мы едем на дачу. = We are going to the dacha (now / on this trip).
• Мы часто ездим на дачу. = We often go to the dacha.
