Меня тошнит после поездки.

Because тошнит is usually used as an impersonal verb in Russian.

In this pattern, the person who feels sick is put in the accusative case:

• меня тошнит = I feel nauseous / I feel sick
• тебя тошнит = you feel nauseous
• его/её тошнит = he/she feels nauseous

So меня here does not mean a direct object in the usual English sense. It is just the standard Russian structure for this expression.

A rough literal idea is something like it nauseates me, even though English normally says I feel sick.

The dictionary form is тошнить.

In this sentence, тошнит is the 3rd person singular present/future-simple form of an imperfective verb, but here it is used impersonally.

So:

• тошнить = to cause nausea / to feel nauseous
• меня тошнит = I feel nauseous

Even though the form is 3rd person singular, there is no real subject stated.

Normally, no, not for the meaning I feel nauseous.

The usual Russian way is:

• Меня тошнит

Russian does not usually express this idea with a normal personal subject like я. So a learner should treat меня тошнит as a fixed common pattern.

Because the preposition после always requires the genitive case.

The noun поездка changes like this:

• nominative: поездка
• genitive: поездки

So:

• после поездки = after the trip / after the ride

This is a very common rule in Russian: certain prepositions always control a specific case, and после takes the genitive.

Поездка usually means a trip, ride, journey, or outing.

In this sentence, после поездки could mean:

• after the trip
• after the ride
• after traveling somewhere

The most natural English translation depends on context. For example:

• after a car ride
• after a bus trip
• after a journey

So поездка is fairly broad.

Not necessarily, but it can.

Меня тошнит после поездки literally says that the speaker feels nauseous after the trip/ride. Depending on context, that could mean:

• motion sickness after traveling
• feeling sick for some other reason that happened after the trip

If you want to be more specific about motion sickness, Russian often uses verbs like укачивать / укачать:

• Меня укачало в машине = I got carsick in the car

So the given sentence is natural, but it is a bit broader than a specifically motion-sickness-only expression.

It is in the present tense.

But in Russian, the present tense is often used for a current state:

• Меня тошнит = I feel sick / I am nauseous

So even though English may use I am feeling sick, Russian simply uses the present form тошнит.

If you wanted the past, you would say:

• Меня тошнило = I felt sick / I was nauseous

Yes. Russian word order is flexible.

The neutral order here is:

• Меня тошнит после поездки.

But you could also say:

• После поездки меня тошнит.

Both are grammatical. The difference is mainly emphasis:

• Меня тошнит после поездки focuses first on the feeling
• После поездки меня тошнит highlights after the trip

So the meaning stays the same, but the information focus changes a little.

They are similar, but not exactly identical.

• Меня тошнит = I feel nauseous / sick
• Мне тошно = I feel sick / nauseous, but it can also sound a bit broader or more emotional depending on context

In many everyday situations, both can work. But меня тошнит is very direct and specifically about nausea.

So if you want to say I feel like I might throw up, меня тошнит is often the clearer choice.

It is neutral everyday Russian.

It is perfectly normal in ordinary speech and writing. It is not especially formal, and it is not slang.

So a learner can safely use:

• Меня тошнит после поездки.

in normal conversation if they want to say they feel sick after a trip or ride.
