Мы переждали ветер; переохлаждения не было.

Not quite. Переждать means to wait something out or to wait until something passes.

So:

• ждать = to wait
• переждать = to wait through / wait out

In this sentence, Мы переждали ветер means something like:

• We waited out the wind
• We waited until the wind passed

The prefix пере- adds the idea of getting through a period of something.

Because ветер is the direct object of переждали, and with this verb the thing being waited out is in the accusative case.

For the noun ветер:

• nominative: ветер
• accusative: ветер

These forms are the same because ветер is:

• masculine
• singular
• inanimate

For many masculine inanimate nouns in Russian, the accusative singular looks exactly like the nominative singular.

So:

• Мы переждали ветер = We waited out the wind

Переждали is perfective past.

That matters because the sentence describes a completed result:

• they waited out the wind
• that event is over
• then we get the outcome: переохлаждения не было

If you used an imperfective form, the focus would be more on the process of waiting, not on the fact that it was successfully completed.

So переждали fits well because the sentence is about:

1. a completed action
2. a resulting state

Because after negated existence in Russian, the thing that does not exist is usually put in the genitive case.

Here the structure is:

• не было = there was not / there wasn’t
• переохлаждения = genitive singular of переохлаждение

So literally:

• There was no hypothermia

This is a very common Russian pattern:

• Времени не было = There was no time
• Ошибок не было = There were no mistakes
• Переохлаждения не было = There was no hypothermia

So the genitive here is caused by the existential negation.

This is an impersonal/existential construction.

In Russian, не было often works like English there was not. It does not need a normal subject in the nominative.

So:

• переохлаждения не было

is not structured like X did not exist with a regular subject. It is more like:

• There was no X

That is why было appears in the neuter singular past form, which is standard in this kind of construction.

Yes, it is natural Russian, though it does sound somewhat clinical or matter-of-fact.

Переохлаждение means hypothermia or overcooling/chilling of the body, depending on context. So the sentence sounds a bit formal or factual, perhaps like a report or summary.

A more conversational Russian sentence might use a different wording, depending on context, for example:

• Мы не переохладились = We didn’t get hypothermic / We didn’t get too cold

But переохлаждения не было is perfectly normal, especially in a neutral, descriptive, or medical tone.

The semicolon links two closely related complete clauses:

• Мы переждали ветер
• переохлаждения не было

It shows a stronger break than a comma, but a closer connection than a full stop.

The effect is roughly:

• first, the action
• second, the result/consequence

A period would also be possible in many contexts:

• Мы переждали ветер. Переохлаждения не было.

That would sound a little more separated. The semicolon makes the link between the two parts especially clear.

Yes, very much so.

The sentence strongly suggests:

• We waited out the wind
• as a result, there was no hypothermia

The second clause feels like the consequence or outcome of the first one, even though Russian does not explicitly say therefore or so.

That is one reason the semicolon works well here: it connects the two ideas while keeping them as separate statements.

Yes, Russian word order is flexible, but the current version is neutral and clear:

• Мы переждали ветер; переохлаждения не было.

You could change the order for emphasis, but it would affect the focus. For example:

• Ветер мы переждали; переохлаждения не было.

This emphasizes ветер more, as if contrasting it with something else.

The original word order is the most straightforward for a learner to treat as the default.

The dictionary forms are:

• мы = we
• переждать = to wait out
• ветер = wind
• переохлаждение = hypothermia / overcooling
• быть = to be

Forms used in the sentence:

• переждали = past tense, plural, perfective
• ветер = accusative singular
• переохлаждения = genitive singular
• было = past tense, neuter singular of быть

A very literal translation would be:

• We waited out the wind; there was no hypothermia.

That is understandable, but depending on context, more natural English might be:

• We waited until the wind died down, and no one got hypothermia.
• We rode out the wind; there was no hypothermia.
• We waited out the wind, so there was no hypothermia.

The Russian is concise and slightly formal, so the best English translation depends on tone.
