Περπατάω μέχρι τη γέφυρα και μετά γυρίζω σπίτι.

Greek often leaves out subject pronouns because the verb ending already shows the person.

• Περπατάω = I walk / I am walking
• γυρίζω = I return / I’m returning

So εγώ is not necessary unless you want emphasis, contrast, or clarity.

For example:

• Περπατάω μέχρι τη γέφυρα. = I walk as far as the bridge.
• Εγώ περπατάω, δεν τρέχω. = I’m walking, not running.

Περπατάω means I walk or I am walking.

It comes from περπατάω / περπατώ, meaning to walk.

In this sentence, it describes the action of going on foot:

• Περπατάω μέχρι τη γέφυρα = I walk as far as the bridge

It is not the general verb to go. If you used πάω, that would just mean I go, without specifically saying that you go on foot.

Both are correct.

• Περπατάω is very common in everyday speech
• Περπατώ is also correct, but can sound a little more concise, slightly more formal, or stylistically neutral depending on context

So:

• Περπατάω μέχρι τη γέφυρα
• Περπατώ μέχρι τη γέφυρα

Both mean the same thing.

This kind of double form is common in Modern Greek verbs.

Here μέχρι means up to, until, or as far as.

So:

• μέχρι τη γέφυρα = up to the bridge / as far as the bridge

It marks the endpoint of the walking.

Be careful: μέχρι can be used with places, time, or other limits.

Examples:

• μέχρι αύριο = until tomorrow
• μέχρι εδώ = up to here
• μέχρι τη γέφυρα = up to the bridge

Because γέφυρα is the object of μέχρι, so it appears in the accusative case.

The noun is:

• nominative: η γέφυρα = the bridge
• accusative: τη γέφυρα = the bridge

So after μέχρι, Greek commonly uses the accusative:

• μέχρι τη γέφυρα

This is a very common pattern in Greek: the article changes with the case.

και μετά means and then or and after that.

It links the two actions in sequence:

1. Περπατάω μέχρι τη γέφυρα
2. μετά γυρίζω σπίτι

So the idea is:

• first I walk to the bridge
• then I go back home

Here μετά is an adverb, not a preposition.

This is a very common question.

In your sentence, μετά means then / afterwards:

• και μετά γυρίζω σπίτι = and then I go back home

But μετά από is usually used before a noun or time expression to mean after:

• μετά από μία ώρα = after an hour
• μετά από το μάθημα = after the lesson

So:

• μετά = then / afterwards
• μετά από + noun/time = after ...

Because Greek often says home without a preposition in expressions of motion, much like English says go home rather than go to home.

So:

• γυρίζω σπίτι = I return home / I go back home

This is a very natural Greek expression.

Compare:

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

If you say γυρίζω στο σπίτι, that is also possible, but it sounds a bit more like I return to the house/home as a destination, rather than the more idiomatic home expression.

It can mean both, depending on context.

• house = the physical building
• home = the place where you live / your home

In γυρίζω σπίτι, it usually means home.

So in this sentence, the natural meaning is:

• I go back home

not just I return to the house in a purely physical sense.

Γυρίζω is a very common everyday verb with several meanings, including:

• turn
• go back
• come back
• return

In this sentence, it means go back / return:

• γυρίζω σπίτι = I go back home

It is similar to επιστρέφω, which also means return, but γυρίζω is often more common in everyday speech.

Examples:

• Γυρίζω σπίτι στις έξι. = I return home at six.
• Επιστρέφω σπίτι στις έξι. = I return home at six.

Both are correct, but γυρίζω often sounds more conversational.

Both verbs are in the present tense:

• Περπατάω
• γυρίζω

In Greek, the present tense can describe:

• something habitual: I walk to the bridge and then go back home
• a usual routine
• a vivid description of what happens

So depending on context, this sentence could mean something like:

• I walk to the bridge and then go back home
• I’m walking to the bridge and then going back home

The exact English translation depends on context, but the Greek form is present tense.

The sentence’s word order is natural and straightforward, but Greek word order is more flexible than English.

The basic sentence is:

• Περπατάω μέχρι τη γέφυρα και μετά γυρίζω σπίτι.

You could move things around for emphasis, for example:

• Μέχρι τη γέφυρα περπατάω και μετά γυρίζω σπίτι.
• Και μετά γυρίζω σπίτι.

But the original version is the most neutral and natural for a learner to use.

Greek often changes word order to highlight a particular part of the sentence, but the standard order here is perfectly good.
