Στο μάθημα φέρνω το λάπτοπ μου, αλλά στο λεωφορείο προτιμώ να διαβάζω από το τάμπλετ.

Στο is a contraction of σε + το.

• σε = in / at / to / on (depending on context)
• το = the for a neuter noun

So:

• στο μάθημα = in class / at the lesson
• στο λεωφορείο = on the bus

Greek very often combines σε with the definite article:

• σε + το = στο
• σε + τη(ν) = στη(ν)
• σε + τους = στους, etc.

So this is a very common pattern to recognize.

Because both nouns are neuter singular.

• το μάθημα = the lesson / the class
• το λεωφορείο = the bus

In Greek, every noun has grammatical gender: masculine, feminine, or neuter. The article must match the noun’s gender, number, and case.

Here, after σε, both nouns appear with the article το, which tells you they are neuter singular.

It is often more natural to understand στο μάθημα as in class or during class.

Literally, it is connected to the lesson/class session, not necessarily just the physical classroom. So it can refer to the context or time of the class, not only the place.

A learner should notice that Greek often uses expressions like this where English may choose a more idiomatic translation.

Because when μου means my, it usually comes after the noun in Greek.

So:

• το λάπτοπ μου = my laptop
• το βιβλίο μου = my book
• η τσάντα μου = my bag

This is one of the big differences from English. Greek possessive weak pronouns such as μου, σου, του, της, μας, σας, τους normally follow the noun.

So the word order is very natural here:

• το λάπτοπ μου = literally the laptop my

Φέρνω means I bring.

It is used because the speaker is talking about bringing the laptop along to class. In other words, the laptop accompanies the speaker to that place.

This is different from verbs like:

• παίρνω = I take
• κουβαλάω = I carry

In many contexts, English bring and take are split differently in Greek depending on viewpoint. Here φέρνω is a very natural choice for I bring my laptop to class.

Because Modern Greek does not use an infinitive the way English does.

English says:

• I prefer to read

Greek expresses this with:

• προτιμώ να διαβάζω

The word να introduces a verb clause, often roughly corresponding to English to before a verb, but it is not an infinitive marker in the same way English uses one.

So a useful pattern is:

• θέλω να... = I want to...
• μπορώ να... = I can...
• προτιμώ να... = I prefer to...

This is one of the most important structural differences between English and Greek.

This is about aspect, which is very important in Greek.

• να διαβάζω = imperfective aspect
• να διαβάσω = perfective aspect

Here, να διαβάζω is used because the meaning is I prefer reading / I prefer to read in a general, habitual, ongoing sense. It focuses on the activity itself.

By contrast, να διαβάσω would sound more like to read something through / to do the reading as a complete action, depending on context.

So in this sentence, the speaker is talking about a general preference while on the bus, which makes να διαβάζω the natural choice.

Here από το τάμπλετ means something like on/from the tablet, in the sense of using the tablet as the source or medium for reading.

The preposition από often means from, but Greek uses it in some places where English would prefer a different preposition.

So:

• διαβάζω από το τάμπλετ = I read on/from the tablet

The idea is that the content is being read from that device. This is a very natural Greek way to say it.

English might say:

• read on the tablet
• read from the tablet

Greek commonly uses από here.

They are loanwords from English, adapted into Greek spelling:

• λάπτοπ
• τάμπλετ

In everyday Greek, words like these are often treated as indeclinable or only minimally changed, especially in casual use. That means the noun itself may stay the same, while the article shows its grammatical role.

For example:

• το λάπτοπ
• του λάπτοπ
• το τάμπλετ
• στο τάμπλετ

In practice, the article often carries the main grammatical information, while the borrowed noun stays unchanged.

Greek has relatively flexible word order, and putting the place expression first is very natural when the speaker wants to set up a contrast.

So the sentence is structured like this:

• Στο μάθημα ... = In class ...
• αλλά στο λεωφορείο ... = but on the bus ...

This makes the contrast especially clear:

• in one situation, the speaker does one thing
• in another situation, the speaker prefers something else

English can do this too, but Greek often uses fronting like this very naturally for emphasis or organization.

Αλλά means but.

It introduces a contrast between the two parts of the sentence:

• Στο μάθημα φέρνω το λάπτοπ μου
• αλλά στο λεωφορείο προτιμώ να διαβάζω από το τάμπλετ

So the speaker is comparing two contexts and two preferences/habits:

• in class → laptop
• on the bus → tablet

This kind of contrastive structure is very common in Greek.

Because Greek normally uses a comma before coordinating words like αλλά when joining two clauses, especially when each clause has its own verb.

Here the two clauses are:

• Στο μάθημα φέρνω το λάπτοπ μου
• αλλά στο λεωφορείο προτιμώ να διαβάζω από το τάμπλετ

Since both are full clauses, the comma is standard and helps mark the contrast clearly.

Yes. Prepositions do not always match one-for-one across languages.

Greek uses σε in many places where English chooses:

• in
• at
• to
• on

So:

• στο λεωφορείο is the normal way to say on the bus
• στο σχολείο = at school
• στο σπίτι = at home / in the house

This is something learners get used to through exposure rather than by expecting exact English-style preposition choices.

It can be followed by either, depending on what you want to say.

With a noun:

• Προτιμώ το τάμπλετ. = I prefer the tablet.

With a να clause:

• Προτιμώ να διαβάζω από το τάμπλετ. = I prefer to read from the tablet.

In your sentence, the speaker is not just preferring the tablet as an object, but preferring the activity of reading from the tablet, so the να + verb structure is the right one.
