На даче дети часто ходят босиком по тёплой траве, если нет дождя.

With дача, Russian normally uses на, not в, when talking about being at the summer house/property in general.

• на даче = at the dacha / out at the country house
• ехать на дачу = to go to the dacha
• быть на даче = to be at the dacha

This is just the standard Russian collocation. Even though a dacha is a house, the phrase refers more broadly to the whole place/property/lifestyle, so на даче is the natural choice.

If you said в даче, it would sound unnatural in normal speech.

A дача is a country house or summer house, often with a garden plot. It is a very culturally specific Russian word.

So на даче does not just mean physically inside a building. It often suggests being out in the countryside, spending time at the family’s summer place, gardening, relaxing, and so on.

That cultural meaning is why Russian learners usually keep the word dacha rather than translating it too literally.

Ходят is the correct choice because this sentence describes a habitual, repeated action:

• дети часто ходят = the children often go / walk

Russian distinguishes between:

• идти / идут = going in one direction right now, at this moment
• ходить / ходят = going habitually, repeatedly, or in various directions

Since часто means often, the sentence is about something that happens regularly, not one specific trip. So ходят fits perfectly.

Compare:

• Дети идут по траве. = The children are walking across the grass right now.
• Дети часто ходят по траве. = The children often walk on/across the grass.

Russian ходить can correspond to both go and walk, depending on context.

Here, the rest of the sentence makes it clear that actual walking is meant:

• босиком = barefoot
• по тёплой траве = on/through the warm grass

So in English, walk barefoot on the warm grass sounds more natural than go barefoot on the warm grass, even though the Russian verb is still ходить.

Босиком means barefoot, and in modern Russian it functions as an adverb.

So:

• ходить босиком = to walk barefoot
• бегать босиком = to run barefoot

It looks like an old instrumental-form word historically, but for learners it is easiest to treat it as a fixed adverb meaning barefoot.

You do not need to change its ending here:

• дети ходят босиком
• я хожу босиком
• она ходит босиком

It stays the same.

Not in the same way.

• босиком describes how someone walks: barefoot
• босые is an adjective meaning barefoot / bare-footed in the sense of having bare feet

Compare:

• Дети ходят босиком. = The children walk barefoot.
• Дети босые. = The children are barefoot.

So in this sentence, because the idea is how they walk, босиком is the natural word.

After по in this meaning, Russian normally uses the dative case.

So:

• трава = grass
• по траве = on the grass / along the grass / through the grass

That is why трава becomes траве.

In this sentence, по тёплой траве means something like:

• on the warm grass
• across the warm grass
• through the warm grass

The exact English preposition depends on context, but the Russian structure is very normal: по + dative.

Because the adjective has to agree with траве, which is in the dative singular.

Base forms:

• тёплая трава = warm grass

After по, we need the dative:

• по тёплой траве

So both words change:

• тёплая → тёплой
• трава → траве

This is standard adjective-noun agreement in Russian.

Because нет requires the genitive case.

So:

• дождь = rain
• нет дождя = there is no rain

This is one of the most important Russian patterns to remember:

• нет времени = there is no time
• нет воды = there is no water
• нет дождя = there is no rain

So дождя is genitive singular, used because of нет.

It actually can. Russian word order is flexible.

Both are possible:

• если нет дождя
• если дождя нет

But если нет дождя is the more neutral, straightforward version here.

Russian often places нет before the noun in simple existential phrases:

• нет времени
• нет денег
• нет дождя

If you move дождя before нет, that can sound a bit more contrastive or stylistically marked depending on context.

No. In Russian, the present tense is often used for habitual actions, just like in English.

• дети часто ходят = the children often walk / usually walk

This does not mean they are necessarily doing it at this exact moment. It describes a general habit or repeated situation.

The word часто strongly supports that habitual meaning.

That is a natural neutral word order in Russian:

• дети часто ходят босиком...

Russian adverbs like часто are often placed before the verb:

• Я часто читаю.
• Мы редко ездим.
• Они обычно приходят рано.

Could the order change? Yes:

• На даче часто дети ходят босиком...
• Дети ходят босиком по тёплой траве часто...

But those versions sound less neutral or put emphasis in different places. The original order is the most natural everyday phrasing.

Because если нет дождя is a subordinate clause:

• main clause: На даче дети часто ходят босиком по тёплой траве
• subordinate clause: если нет дождя

Russian normally uses a comma before если when it introduces a conditional clause, just as English often separates if-clauses.

So the comma here is standard punctuation.

Here по expresses movement over a surface or within an area.

So по тёплой траве can be translated in different ways depending on what sounds best in English:

• on the warm grass
• across the warm grass
• through the warm grass

Russian по is broader than any one English preposition here. The important thing is that it suggests movement over the grass rather than just location.

Yes. ё is pronounced yo, so:

• тёплой sounds roughly like TYOP-loy

In printed Russian, ё is sometimes written as е, so you may also see теплой, but the correct pronunciation is still with yo in this word.

So:

• written carefully: тёплой
• often written in ordinary texts: теплой
• pronounced: tyoploy

Yes:

• Дети часто ходят босиком по тёплой траве на даче, если нет дождя.

That is grammatically possible. But starting with На даче sets the scene first, which feels very natural in Russian.

Russian word order is flexible, and moving elements changes emphasis:

• На даче first = the setting is introduced first
• Дети first = the children become the main topic first

The original version sounds smooth and natural because it begins with the context.
