Η αδερφή μου αγόρασε άλλο ένα λουλούδι για τη μικρή γλάστρα δίπλα στην πόρτα.

Greek often uses the definite article with family members and possessive expressions, much more than English does. So Η αδερφή μου literally looks like the sister of me, but it simply means my sister.

Using the article here is completely normal and expected in Greek.

μου means my, but grammatically it is actually the weak genitive form of εγώ. In other words, Greek often expresses possession with a small pronoun placed after the noun.

So:

• η αδερφή μου = my sister
• το σπίτι μου = my house
• ο φίλος μου = my friend

This is one of the most common ways Greek shows possession.

That is the normal Greek pattern for these short possessive pronouns.

So Greek says:

• η αδερφή μου = my sister
• το βιβλίο σου = your book
• ο πατέρας της = her father

This is different from English, where my, your, his, her usually come before the noun.

αγόρασε is the aorist form, which is the basic past tense for a completed action.

Here it means:

• she bought

More specifically, it is:

• 3rd person singular
• aorist
• active voice

The verb is αγοράζω = I buy Its aorist stem changes, giving αγόρασα = I bought, so:

• αγόρασα = I bought
• αγόρασες = you bought
• αγόρασε = he/she/it bought

άλλο ένα means another one or one more.

So:

• ένα λουλούδι = a flower
• άλλο ένα λουλούδι = another flower / one more flower

Here άλλο agrees with λουλούδι, which is neuter singular, so it appears in the neuter singular form άλλο.

Compare:

• άλλος φίλος = another friend (masculine)
• άλλη γλάστρα = another pot (feminine)
• άλλο λουλούδι = another flower (neuter)

λουλούδι is a neuter noun. Many neuter nouns in Greek end in -ι, and in the singular the nominative and accusative forms are often the same.

Here λουλούδι is the direct object of αγόρασε, so it is in the accusative, but the form looks the same as the dictionary form.

So:

• το λουλούδι = the flower
• αγόρασε το λουλούδι = she bought the flower

The preposition για usually takes the accusative case. That is why τη μικρή γλάστρα is in the accusative.

Breakdown:

• τη = feminine singular accusative article
• μικρή = feminine singular accusative adjective
• γλάστρα = feminine singular accusative noun

So the whole phrase means:

• for the small pot

In Greek, adjectives often come before the noun, just as in English.

So:

• η μικρή γλάστρα = the small pot

That is the most straightforward order. Greek can sometimes move adjectives around for emphasis or style, but μικρή γλάστρα is the neutral, standard order.

Both τη and την are forms of the feminine accusative singular article. In modern Greek, the final -ν is often dropped before certain sounds and kept before others.

So you may see both:

• τη γλάστρα
• την πόρτα

In everyday language, this depends on pronunciation, spelling conventions, and style. Learners should recognize both as the same article in this kind of context.

γλάστρα means flowerpot, plant pot, or pot for a plant.

In this sentence, για τη μικρή γλάστρα means the flower was bought for the small pot, meaning the pot is probably going to contain that flower.

δίπλα means next to or beside, but it is usually followed by a prepositional phrase, often with σε.

So:

• δίπλα στην πόρτα = next to the door

This is basically:

• δίπλα = next to
• στην πόρτα = at/to the door

Together they form the natural Greek expression for next to the door.

στην is a contraction of σε + την.

This happens very often in Greek:

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

So:

• στην πόρτα = σε την πόρτα

The contracted form is the normal one in everyday Greek.

After the preposition σε, Greek uses the accusative case in modern Greek.

So in στην πόρτα:

• στην = σε + την
• πόρτα is accusative feminine singular

Even though English says next to the door, Greek still uses the accusative after σε.

In this sentence, the most natural interpretation is that it describes the pot:

• for the small pot next to the door

So the pot is next to the door, not necessarily the flower by itself.

Greek word order and proximity strongly suggest that δίπλα στην πόρτα attaches to τη μικρή γλάστρα.

Yes. Greek word order is more flexible than English word order, because case endings and articles help show the grammatical relationships.

For example, Greek could move parts around for emphasis, such as:

• Η αδερφή μου αγόρασε για τη μικρή γλάστρα άλλο ένα λουλούδι.

This still means roughly the same thing, though the focus may shift slightly. The original version is very natural and neutral.

Greek verbs already show the person and number, so a separate subject pronoun is often unnecessary.

αγόρασε already tells you the subject is:

• he/she/it bought

Since the noun Η αδερφή μου is present, there is no need to add αυτή.

Greek commonly omits subject pronouns unless they are needed for emphasis or contrast.

Both exist.

• αδερφή is very common in everyday modern Greek
• αδελφή is a more conservative or formal variant

A native speaker would immediately understand either one. For learners, αδερφή is very useful because it matches common spoken Greek very well.

You can often tell from the article and the noun ending:

• η αδερφή = feminine
• το λουλούδι = neuter
• η γλάστρα = feminine
• η πόρτα = feminine

The article is one of the best clues in Greek, so it is a good habit to learn nouns together with their article:

• η αδερφή
• το λουλούδι
• η γλάστρα
• η πόρτα

That will help you remember both gender and case patterns.
