Η γιαγιά μου λέει ότι κι εκείνη νοσταλγεί την παλιά αυλή, όπου καθόταν με τον παππού μου τα καλοκαίρια.

Both are possible.

• Η γιαγιά μου = my grandmother / grandma
• γιαγιά μου can also mean my grandmother, especially in more informal speech

Greek often uses the definite article where English would not. So Η γιαγιά μου is completely natural and very common.

In this sentence, the article helps present the subject clearly: My grandmother says...

Here μου means my.

Greek usually expresses possession with a weak genitive pronoun placed after the noun:

• η γιαγιά μου = my grandmother
• ο παππούς μου = my grandfather

So instead of a separate word like English my before the noun, Greek often uses μου after it.

Ότι means that and introduces a content clause, just like English:

• λέει ότι... = she says that...

So:

• Η γιαγιά μου λέει ότι...
  = My grandmother says that...

In everyday Greek, πως can often be used in a similar way:

• λέει πως...
• λέει ότι...

Both are common.

κι is a shortened form of και, meaning and.

Before words beginning with a vowel, Greek often uses κι instead of και because it sounds smoother:

• κι εκείνη instead of και εκείνη

So here:

• κι εκείνη = and she too / and she as well

It is not a different word in meaning, just a shorter form.

Greek often drops subject pronouns because the verb ending already shows the person. But pronouns are included when they add emphasis, contrast, or clarity.

Here κι εκείνη means something like:

• and she too
• she as well
• even she

So εκείνη is not just a basic subject pronoun here; it adds emphasis. It suggests that someone else also feels nostalgic, and the grandmother does too.

Yes. εκείνη is the feminine form of that one and can also function as she in certain contexts.

Forms:

• εκείνος = masculine
• εκείνη = feminine
• εκείνο = neuter

In this sentence, εκείνη refers back to η γιαγιά, so it means she with emphasis:

• κι εκείνη νοσταλγεί... = she too misses / feels nostalgic for...

Νοσταλγεί is the present tense, 3rd person singular, from νοσταλγώ = to miss / long for / feel nostalgic for.

• νοσταλγεί = she misses / she longs for / she feels nostalgic for

Greek often uses the present here exactly as English does. The meaning is that this feeling exists now.

So:

• κι εκείνη νοσταλγεί την παλιά αυλή
  = she too misses the old courtyard

Because this is the direct object of νοσταλγεί.

The verb νοσταλγώ takes a direct object, so the noun phrase goes into the accusative:

• nominative: η παλιά αυλή
• accusative: την παλιά αυλή

Both the article and the adjective must agree with the noun:

• την = feminine singular accusative article
• παλιά = feminine singular accusative adjective
• αυλή = feminine singular accusative noun

So Greek shows grammar through these forms.

Αυλή usually means yard or courtyard.

Depending on context, it can refer to:

• the yard of a house
• an inner courtyard
• a schoolyard

In this sentence, την παλιά αυλή is best understood as the old courtyard/yard, probably a familiar family place connected with memories.

It is not usually the same as garden in the English sense. For garden, Greek would more often use κήπος.

Όπου means where and introduces a relative clause referring to a place.

So:

• η παλιά αυλή, όπου καθόταν...
• the old courtyard, where she used to sit...

It connects the place (the old courtyard) with what happened there.

Καθόταν is the imperfect tense of κάθομαι (to sit / be sitting).

The imperfect is often used for:

• repeated actions in the past
• habitual actions
• ongoing background situations in the past

Here it means something like:

• she used to sit
• she would sit
• she was sitting (in a repeated/habitual sense)

Because the sentence mentions τα καλοκαίρια (in the summers / every summer), the imperfect is especially appropriate: it describes a repeated past habit.

The basic verb here is κάθομαι, which means to sit / to be seated.

Its imperfect is:

• καθόμουν / καθόμουνα
• καθόσουν
• καθόταν
• etc.

So καθόταν is the normal 3rd person singular imperfect form of κάθομαι.

A different verb, καθίζω, can mean I seat someone / I sit someone down, or in some contexts I sit down, but that is not the most natural choice here. The sentence is simply describing where she used to sit.

Με means with, and it is followed by the accusative in Modern Greek.

So:

• ο παππούς μου = my grandfather (nominative)
• τον παππού μου = my grandfather (accusative)

Therefore:

• με τον παππού μου = with my grandfather

This is completely normal Greek grammar: many prepositions, including με, are followed by the accusative.

Yes. μου is still fine and natural.

The speaker says:

• Η γιαγιά μου = my grandmother
• τον παππού μου = my grandfather

From the speaker’s point of view, both people are my grandparents. Greek expresses that directly.

Even though the subject is the grandmother, the possession remains anchored to the speaker, not to the grandmother.

Τα καλοκαίρια literally means the summers, but in context it often means:

• in the summers
• during the summer months
• every summer
• summer after summer

Greek commonly uses the plural with the article to express repeated time periods.

So here it suggests a habitual past memory:

• she used to sit there with my grandfather in the summers / every summer

Yes, usually.

• το καλοκαίρι = in the summer or this summer / the summer, depending on context
• τα καλοκαίρια = in the summers / every summer / during summers generally

So the plural here gives a repeated, habitual feeling, which fits well with καθόταν.

It breaks down like this:

• Η γιαγιά μου λέει
  = My grandmother says

• ότι κι εκείνη νοσταλγεί την παλιά αυλή
  = that she too misses the old courtyard

• όπου καθόταν με τον παππού μου τα καλοκαίρια
  = where she used to sit with my grandfather in the summers

So the sentence has:

1. a main clause: Η γιαγιά μου λέει
2. a subordinate clause introduced by ότι
3. a relative clause introduced by όπου

Yes, Greek word order is more flexible than English word order, although not completely free.

The given order is natural because it flows clearly:

• subject: Η γιαγιά μου
• verb: λέει
• clause: ότι...

Inside the clause, κι εκείνη comes early because it is emphatic: she too.

You could change some parts for emphasis, but the original sentence is very natural and balanced.

The sentence has a warm, nostalgic tone.

Important clues:

• κι εκείνη adds the sense she too
• νοσταλγεί expresses longing or nostalgia
• την παλιά αυλή points to a specific remembered place
• καθόταν... τα καλοκαίρια suggests a repeated, cherished scene from the past

So the feeling is not just factual. It evokes memory, family, and shared longing for an old home place.
