Il mio autobus passa alle tredici e diciotto, quindi ho tempo per un caffè.

In Italian, possessives like mio, tuo, and suo usually take a definite article, so il mio autobus is the normal way to say my bus.

A few quick notes:

• il matches autobus, which is masculine singular
• mio agrees with autobus, not with the speaker
• Italian often uses the article with possessives more than English does

So:

• il mio autobus = my bus
• la mia macchina = my car
• i miei amici = my friends

One common exception is with many singular family members:

• mio padre = my father
• mia sorella = my sister

But autobus is not a family member, so il mio autobus is correct.

Autobus is the standard general word for bus in Italian. It is very common in everyday language.

Some related words:

• autobus = bus
• bus = also used, especially in speech
• pullman = usually a coach or long-distance bus, not always a normal city bus

So in this sentence, autobus is the safest and most neutral choice.

Yes, passa literally comes from passare, meaning to pass. In transport contexts, it often means:

• comes by
• passes
• goes past
• is due to come through

So Il mio autobus passa alle tredici e diciotto means something like:

• My bus comes by at 13:18
• My bus passes at 13:18

In natural English, we often just say My bus leaves at... or My bus is at..., but Italian commonly uses passare for buses, trains, and similar transport.

Because when telling time in Italian, you normally use a + definite article:

• all'una = at one
• alle due = at two
• alle tredici = at thirteen

Here:

• a + le becomes alle

So:

• alle tredici e diciotto = at 13:18

This is the standard structure for clock times.

Yes. Tredici e diciotto is 13:18, so it uses the 24-hour clock.

Italian uses both 12-hour and 24-hour time, but the 24-hour system is very common, especially for:

• schedules
• transport
• formal situations
• announcements

So:

• 13:18 = tredici e diciotto
• 1:18 p.m. can also be understood in context, but transport schedules usually use the 24-hour form

In more casual conversation, people may also say:

• l'una e diciotto

But for a bus schedule, tredici e diciotto sounds very natural.

Yes, in some contexts you could, because both refer to 1:18 p.m. But there is a difference in style and clarity.

• all’una e diciotto = more conversational
• alle tredici e diciotto = more precise, more like timetable language

Since this sentence is about a bus, alle tredici e diciotto sounds especially appropriate because transport times are often given in the 24-hour format.

Quindi means therefore, so, or thus.

It connects the two ideas:

• My bus passes at 13:18
• therefore / so
• I have time for a coffee

So it shows a logical consequence.

Other common connectors you might compare:

• quindi = so, therefore
• allora = so, then
• perciò = therefore
• così = so, thus, in some contexts

In this sentence, quindi is a very natural choice.

Both are possible in Italian, but ho tempo is much more natural here.

• ho tempo = I have time
• ho il tempo = I have the time

In general, when Italian speaks about having enough available time, it often uses avere tempo without the article.

So:

• Ho tempo per un caffè = I have time for a coffee
• Non ho tempo = I don’t have time

Using il would sound more specific, as if referring to a particular amount of time already mentioned.

Yes. Per here means for, and un caffè means a coffee.

The whole phrase avere tempo per qualcosa means:

• to have time for something

Examples:

• Ho tempo per pranzo = I have time for lunch
• Hai tempo per una telefonata? = Do you have time for a phone call?
• Abbiamo tempo per un caffè = We have time for a coffee

So per un caffè is a very normal expression.

It can suggest both, depending on context.

Literally, un caffè means a coffee. But in natural usage, especially in sentences like this, it often implies:

• having a quick coffee
• taking a short coffee break
• stopping for coffee

Since coffee is usually quick in Italy, ho tempo per un caffè naturally suggests a short stop before the bus.

Yes. The full form would be io ho tempo, but Italian usually drops subject pronouns when they are not needed.

That is because the verb ending already tells you who the subject is:

• ho = I have
• hai = you have
• ha = he/she/it has

So ho tempo clearly means I have time.

Italian often omits:

• io
• tu
• lui/lei when the meaning is already clear from the verb.

Both are in the present tense.

• passa = third person singular present of passare
• ho = first person singular present of avere

Even though the sentence refers to a future event, Italian often uses the present tense for scheduled future actions, just like English sometimes does:

• The bus leaves at 1:18
• My train arrives tomorrow
• Il mio autobus passa alle tredici e diciotto

This is very common with timetables and fixed plans.

Because the subject is il mio autobus, which is singular:

• il = singular
• mio = singular
• autobus = singular

So the verb must also be singular:

• Il mio autobus passa = My bus passes

If the subject were plural, the verb would change:

• I miei autobus passano... = My buses pass...

Yes. Autobus usually stays the same in both singular and plural.

So:

• l’autobus = the bus
• gli autobus = the buses

This happens because autobus is a borrowed word and is commonly treated as invariable.

You know whether it is singular or plural from the article or the rest of the sentence:

• il mio autobus passa = singular
• i miei autobus passano = plural

It sounds natural and correct.

It has a slightly orderly, timetable-like feel because of alle tredici e diciotto, but that fits perfectly with talking about a bus.

A native speaker might also say things like:

• Il mio autobus passa all’una e diciotto, quindi ho tempo per un caffè.
• Il bus passa alle 13:18, quindi faccio in tempo a prendere un caffè.

But your original sentence is absolutely normal and idiomatic.
