Όταν γυρίζω σπίτι, αδειάζω την τσάντα μου πάνω στο τραπέζι.

Because in Greek, όταν introduces a time clause meaning when, but with the present tense it often describes a repeated/habitual action. So in natural English, this sentence is often understood as Whenever I get home, I empty my bag onto the table.

So:

• Όταν γυρίζω σπίτι... = When/Whenever I get home...
• habitual meaning comes from the present tense, not from a special separate word for whenever

Greek uses the present tense here to describe a routine or habit.

• γυρίζω = I return / I come back
• αδειάζω = I empty

So the sentence means this is something the speaker usually does, not something happening only right now.

If you wanted a single future event, Greek would normally change the form:

• Όταν γυρίσω σπίτι, θα αδειάσω την τσάντα μου πάνω στο τραπέζι.
• When I get home, I’ll empty my bag onto the table.

Here γυρίζω means come back, return, or get back.

This verb has several meanings in Greek depending on context, including:

• turn
• go around
• return / come back

In this sentence, because it is followed by σπίτι, the meaning is clearly return home.

Because Greek often uses σπίτι by itself in expressions meaning home, especially with verbs of motion such as:

• πάω σπίτι = I go home
• έρχομαι σπίτι = I come home
• γυρίζω σπίτι = I return home

This is very similar to English, where we say go home, not go to home.

So σπίτι here works in an idiomatic, almost adverb-like way.

Yes. Γυρίζω σπίτι and γυρίζω στο σπίτι are both possible.

• γυρίζω σπίτι = very natural, idiomatic I come home / return home
• γυρίζω στο σπίτι = also natural, slightly more explicit as to the house/home

In many everyday situations, the difference is small.

Because in expressions like πάω σπίτι, έρχομαι σπίτι, γυρίζω σπίτι, Greek σπίτι usually means home in English.

So although σπίτι can literally mean house or home, the natural meaning here is home.

It means I empty my bag — in other words, I take the contents out of it.

In context, it can sound like:

• I empty my bag out onto the table
• I unpack my bag onto the table
• I dump everything out of my bag onto the table

It does not mean simply I put my bag on the table.

Because Greek usually expresses possession with a weak possessive pronoun placed after the noun.

So:

• η τσάντα μου = my bag
• literally: the bag my

In the sentence, τσάντα is the direct object, so it becomes:

• την τσάντα μου = my bag in the accusative

This is completely normal Greek word order.

Greek normally uses the definite article with possessed nouns.

So Greek says:

• η φίλη μου = my friend
• το βιβλίο μου = my book
• την τσάντα μου = my bag

That is standard Greek structure. English usually does not use the in these cases, but Greek usually does.

στο is the contraction of:

• σε + το = στο

So:

• στο τραπέζι = on/to the table depending on context

This kind of contraction is very common in Greek:

• σε + τον = στον
• σε + τη(ν) = στη(ν)
• σε + το = στο

πάνω στο τραπέζι means on the table or, with a verb like αδειάζω, often onto the table.

Breakdown:

• πάνω = on top / above
• στο τραπέζι = on/to the table

In this sentence, the idea is that the contents end up on the surface of the table.

A useful contrast:

• πάνω στο τραπέζι = on the table (touching it)
• πάνω από το τραπέζι = above the table (not necessarily touching)

Both are in the accusative, but for different reasons.

• την τσάντα is accusative because it is the direct object of αδειάζω
• στο τραπέζι contains accusative because σε normally takes the accusative

A detail that often confuses learners:

• τραπέζι is neuter singular
• many neuter nouns have the same form in nominative and accusative

So το τραπέζι and στο τραπέζι look very similar, even though the function is different.

The same is true for σπίτι: its nominative and accusative forms are identical.

No. Greek word order is more flexible than English word order.

The original sentence is a neutral, natural way to say it:

• Όταν γυρίζω σπίτι, αδειάζω την τσάντα μου πάνω στο τραπέζι.

You can move things around for emphasis, but the tone changes. For example:

• Όταν γυρίζω σπίτι, την τσάντα μου την αδειάζω πάνω στο τραπέζι.

That gives extra emphasis to the bag.

For learners, the original order is the safest and most natural.

Because Όταν γυρίζω σπίτι is an introductory time clause.

So Greek normally writes:

• Όταν γυρίζω σπίτι, αδειάζω...

The comma separates the time clause from the main clause. It helps readability and is standard punctuation here.

You would normally change the verb forms:

• Όταν γυρίσω σπίτι, θα αδειάσω την τσάντα μου πάνω στο τραπέζι.

That means:

• When I get home, I’ll empty my bag onto the table.

So the contrast is:

• Όταν γυρίζω σπίτι... = habitual, repeated
• Όταν γυρίσω σπίτι... = one future occasion
