Τον Φεβρουάριο η μεσίτρια μού έδειξε ένα φωτεινό διαμέρισμα, αλλά τελικά μετακομίσαμε τον Σεπτέμβριο.

Those month names are in the accusative: Φεβρουάριο, Σεπτέμβριο.

In Greek, time expressions like in February or in September are very often expressed with the accusative + article:

• τον Φεβρουάριο = in February
• τον Σεπτέμβριο = in September

The basic dictionary forms are:

• ο Φεβρουάριος
• ο Σεπτέμβριος

So here they change from nominative to accusative:

• ο Φεβρουάριος → τον Φεβρουάριο
• ο Σεπτέμβριος → τον Σεπτέμβριο

Greek uses the definite article with months in this kind of time expression much more naturally than English does.

So Greek says:

• τον Φεβρουάριο
• τον Σεπτέμβριο

where English simply says:

• in February
• in September

This is normal Greek, not extra emphasis.

Yes. η μεσίτρια means the real-estate agent or the realtor, specifically a female one.

A few things are happening here:

• η = the feminine singular definite article
• μεσίτρια = female real-estate agent / realtor

Greek often uses the article where English might or might not use one, especially when talking about a specific person already understood in the situation.

If it were indefinite, it would be:

• μια μεσίτρια = a real-estate agent

Yes. Greek nouns usually have grammatical gender, and for people this often matches biological sex.

• ο μεσίτης = a male real-estate agent
• η μεσίτρια = a female real-estate agent

In this sentence, the feminine form matters because it matches the person being referred to, and it also matches the article η.

μού means to me.

So:

• η μεσίτρια μού έδειξε... = the real-estate agent showed me...

Grammatically, this is a weak object pronoun. Greek uses these little pronouns a lot:

• μου = to me / my
• σου = to you / your
• του = to him / his
• της = to her / her

Here it is the indirect object of έδειξε: she showed something to me.

Because weak object pronouns in Greek normally come before a finite verb.

So Greek says:

• μού έδειξε = showed me

not a word-for-word English-style order like showed to me.

This is very common in Greek:

• μου είπε = he/she told me
• σου δίνω = I give you
• μας έστειλαν = they sent us

So μού έδειξε is the normal Greek order.

They are the same word. In everyday writing, you will very often see simply μου.

The accented form μού does not change the basic meaning here. It is just an alternative spelling choice that some writers use for clarity or emphasis. As a learner, you should definitely recognize both, but μου is the most common form you will meet.

Because all three words are in the neuter singular accusative, and the adjective agrees with the noun.

• ένα = a / one, neuter singular
• φωτεινό = bright, neuter singular
• διαμέρισμα = apartment, neuter singular

So the adjective φωτεινό has to match διαμέρισμα in gender, number, and case.

This is one of the basic patterns in Greek:

• ένα μεγάλο σπίτι = a big house
• ένα όμορφο δωμάτιο = a beautiful room
• ένα φωτεινό διαμέρισμα = a bright apartment

Because that is a very common position for adjectives in Greek, just as in English.

So:

• ένα φωτεινό διαμέρισμα = a bright apartment

is perfectly normal.

Greek adjectives can sometimes come after the noun too, but before the noun is extremely common, especially in straightforward descriptions.

They are both in the aorist, which is the usual Greek past tense for a completed event.

• έδειξε = she showed
• μετακομίσαμε = we moved

In this sentence, both actions are viewed as whole, completed events:

• at some point in February, the realtor showed the apartment
• later, in September, we moved

So the aorist is exactly what you would expect here.

That έ- is the past-tense augment, but in Modern Greek it does not always appear in the same way.

• δείχνω → έδειξε
• μετακομίζω → μετακομίσαμε

A simple way to think about it is this: in many past forms, Greek adds or keeps an augment when the stress pattern needs it. In longer or compound verbs, there is often no extra ε- at the beginning.

So learners often just memorize the past forms as they meet them:

• δείχνω → έδειξα / έδειξε
• μετακομίζω → μετακόμισα / μετακομίσαμε

Because the verb ending already tells you that.

μετακομίσαμε is first person plural, so it means we moved.

Greek very often leaves subject pronouns out because the verb ending is enough:

• μετακομίσαμε = we moved
• πήγαμε = we went
• είδαμε = we saw

If you added εμείς, it would usually be for emphasis:

• εμείς μετακομίσαμε = we moved / we were the ones who moved

Exactly. μετακομίζω means to move house / change residence.

So:

• μετακομίσαμε τον Σεπτέμβριο = we moved in September

If you wanted to say we moved a table or we moved some boxes, Greek would usually use a different verb, such as μετακινώ or μεταφέρω, depending on the situation.

τελικά means something like in the end, eventually, or after all.

So:

• αλλά τελικά μετακομίσαμε τον Σεπτέμβριο = but in the end we moved in September

It shows that the final outcome was different from what the earlier part of the sentence might lead you to expect. The apartment was shown in February, but the actual move happened only later, in September.

Yes, Greek word order is more flexible than English word order.

This sentence starts with the time phrase:

• Τον Φεβρουάριο ...

That puts early focus on when the first event happened.

The order here is very natural:

• Τον Φεβρουάριο η μεσίτρια μού έδειξε ένα φωτεινό διαμέρισμα

But Greek could rearrange parts of the sentence for emphasis, for example:

• Η μεσίτρια μού έδειξε ένα φωτεινό διαμέρισμα τον Φεβρουάριο

That would still be grammatical, but the focus would be slightly different. Greek uses word order a lot to manage emphasis and information flow.
