Learn Hardcore Russian: Я успел на автобус.

Успел is the masculine past tense of the perfective verb успеть, which means “to manage (in time), to succeed in being on time for something.” Here it states a completed success: you made it in time to catch the bus. The perfective aspect presents the action as a single, finished event.

Why is it успел and not успела/успели?

In the past tense, Russian verbs agree with the subject’s gender and number:

Masculine singular: я успел
Feminine singular: я успела
Neuter singular (for neuter subjects): оно успело
Plural: мы/они успели

Why is it на автобус and not в автобус?

With scheduled transport or events, Russian typically uses на + accusative to mean “make it to/catch” (focus on the departure/event):

успеть на автобус/поезд/самолёт/лекцию
By contrast, в + accusative emphasizes movement into an interior space:
зайти в автобус, сесть в автобус (physically enter/seat yourself in the bus).
So for “catch the bus (in time),” use на автобус.

What case is автобус in here?

Accusative. After на indicating a goal/direction (куда?), you use the accusative. With inanimate masculine nouns like автобус, nominative and accusative look the same. With a feminine noun you’d see the change: успел на электричку.

Can I say успеть в автобус or успеть к автобусу?

Успеть в автобус is unidiomatic; avoid it.
Успеть к автобусу can occur in some contexts (“be in time for the bus” as an arrival deadline), but for “catch the bus” the natural, default choice is успеть на автобус.

How do I say “I missed the bus”?

Two common options:

Я не успел(а) на автобус. (“I didn’t manage to catch the bus.”)
Я опоздал(а) на автобус. (“I was late for the bus.”)
Both imply you missed it. Не успел stresses failure to make it in time; опоздал stresses lateness.

How would I ask “Did you make it to the bus?”

To a man: Ты успел на автобус?
To a woman: Ты успела на автобус?
Polite/plural: Вы успели на автобус?

What’s the difference between успеть and успевать?

They’re a perfective/imperfective pair:

успеть (perfective) = a completed result: Я успел на автобус.
успевать (imperfective) = process/habit: Я обычно успеваю на автобус. / “I usually manage to catch the bus.”
For a near-future prediction/result, use perfective: Я успею на автобус?

How do I say “by bus” as a means of transport versus “for the bus” to catch it?

Means: на автобусе (prepositional case) — “by bus.” Example: Я поехал на автобусе.
Catching: на автобус (accusative) — “for the bus.” Example: Я успел на автобус.

Are there other natural ways to express this idea?

Я сел на автобус. = “I got on/took the bus” (boarding; doesn’t emphasize the race against time).
Я догнал автобус. = “I caught up with the bus” (literally ran after it).
Я поймал автобус. is uncommon; поймать is natural with taxis: поймать такси.
If you want to stress being in time, успеть на автобус is the standard.

How can I specify which bus (number, time, destination)?

Number: успел на автобус № 12 or на двенадцатый автобус.
Time: успел на автобус в восемь or на восьмичасовой автобус.
Destination: успел на автобус до Москвы.

Can I change the word order?

Yes, for emphasis:

На автобус я успел, а на поезд — нет. (Emphasis on “the bus.”)
Я успел на автобус is the neutral, most common order.
Other permutations are possible but can sound marked or stylistic.

Can I drop я?

Russian usually keeps the pronoun, but it can be omitted in short answers or when context is crystal clear:
— Успел на автобус? — Успел.
In a full standalone sentence, keep я.

Any tips on pronunciation and stress?

Stress: Я успе́л на авто́бус.
Approximate transliteration: Ya uspél na avtóbus.
The stressed vowels are е in успе́л and о in авто́бус.
