Мы будем ждать автобус максимум десять минут.

Because ждать is an imperfective verb. In Russian, imperfective verbs make the future with:

быть in the future + infinitive

So:

• мы будем ждать = we will wait / we will be waiting

This often suggests the action as a process or duration, which fits well with десять минут.

A perfective partner such as подождать would form a simple future:

• мы подождём

That sounds more like a single complete waiting event. Both can be possible in some contexts, but будем ждать works very naturally when the sentence emphasizes the length of time.

Here автобус is the direct object of ждать.

In modern Russian, ждать very often takes the accusative, especially with a specific, concrete thing:

• ждать автобус
• ждать поезд
• ждать друга

For a masculine inanimate noun like автобус, the accusative looks the same as the nominative:

• nominative: автобус
• accusative: автобус

So ждать автобус is normal.

You may also encounter ждать автобуса, because ждать has historically been used with the genitive too. But for many everyday learners, ждать + accusative is the safest practical pattern for concrete objects.

Because Russian often uses the accusative to express duration of time directly, without a preposition.

So:

• ждать десять минут = to wait ten minutes
• работать весь день = to work all day
• спать всю ночь = to sleep all night

In this sentence, десять минут means the length of time the waiting will last.

After numbers in Russian, the noun changes form depending on the number.

With 5 and higher, Russian normally uses the genitive plural:

• пять минут
• десять минут
• двадцать минут

That is why the noun is минут.

Compare:

• одна минута
• две / три / четыре минуты
• пять минут

So десять минут is exactly what you should expect.

Максимум here means at most or no more than.

So:

• максимум десять минут = at most ten minutes

It limits the duration. The idea is:

We will wait for the bus no longer than ten minutes.

In this use, максимум behaves like an adverb-like limiting word before the number phrase.

Yes, Russian word order is fairly flexible.

The given sentence is natural:

• Мы будем ждать автобус максимум десять минут.

You could also hear things like:

• Мы максимум десять минут будем ждать автобус.
• Максимум десять минут мы будем ждать автобус.

These are all understandable, but the emphasis changes slightly.

The original version sounds quite neutral. Putting максимум десять минут earlier can give that limit more emphasis.

Yes, very often.

Russian does not require subject pronouns as often as English does, because the verb form already shows the person and number:

• будем = we will

So:

• Будем ждать автобус максимум десять минут.

is perfectly possible.

You keep мы when you want to make the subject explicit, contrast it with someone else, or just sound a little clearer.

Because Russian has no articles like a or the.

So автобус can mean:

• the bus
• a bus

The context tells you which one is meant.

In a sentence like this, English usually says the bus, because both speakers probably know which bus they are talking about. Russian simply uses автобус and leaves that to context.

Yes, in some situations you could say:

• Мы подождём автобус максимум десять минут.

That would also mean something like We’ll wait for the bus for at most ten minutes.

The difference is aspect:

• будем ждать = imperfective future, focusing on the process/duration
• подождём = perfective future, viewing the waiting as one complete event

With a time limit like максимум десять минут, both are possible, but будем ждать can sound especially natural when the sentence stresses the ongoing action of waiting.

More or less, yes. A rough breakdown is:

• Мы = we
• будем = will be / will
• ждать = wait
• автобус = bus / the bus
• максимум = at most / maximum
• десять минут = ten minutes

But natural English needs for in wait for the bus, while Russian does not use a preposition here. So a good natural translation is:

We will wait for the bus for at most ten minutes.
