Μιλάει για την Ελλάδα με τόση αγάπη που θέλω να την ακούω περισσότερο.

Greek often leaves out subject pronouns when they are not needed. The verb form μιλάει already tells you it is third person singular, so the subject can be understood as he/she/it from context.

So Greek says:

• Μιλάει = He/She speaks / is speaking

Adding αυτός or αυτή is possible, but usually only for emphasis or contrast.

Μιλάει is the 3rd person singular present of μιλάω / μιλώ, meaning to speak.

So:

• μιλάει = he/she speaks
• μιλά = also he/she speaks

Both are normal in Modern Greek. Μιλάει is simply a fuller form, while μιλά is a shorter alternative. A learner will see both very often.

The preposition για here means about.

So:

• μιλάει για... = he/she talks about...

Για is followed by the accusative, which is why you get:

• η Ελλάδα = Greece as the subject form
• την Ελλάδα = Greece after για

So για την Ελλάδα means about Greece.

In Modern Greek, the feminine accusative article/pronoun can appear as τη or την. The final -ν is normally kept before a vowel and before certain consonants.

Here both following words begin with a vowel:

• την Ελλάδα
• την ακούω

So την is the expected form.

Greek uses the definite article much more often than English, including with many proper nouns, especially country names.

So Greek naturally says:

• η Ελλάδα = Greece
• την Ελλάδα = Greece in the accusative

Even though English usually says just Greece, Greek normally includes the article.

This is a very useful Greek pattern:

• τόσος / τόση / τόσο ... που = so much / so ... that

In this sentence:

• με τόση αγάπη = with so much love
• που θέλω... = that I want...

So the whole stretch means:

• with so much love that I want...

Also, τόση agrees with αγάπη, which is a feminine singular noun.

Modern Greek does not use the old infinitive the way English does. Instead, it usually uses:

• θέλω να + verb

So:

• θέλω να ακούω = literally I want that I listen, but naturally I want to listen

This is one of the most basic Greek patterns:

• θέλω να πάω = I want to go
• θέλω να δω = I want to see
• θέλω να μιλήσω = I want to speak

This την refers to the person who is speaking, not to Greece.

That is a very important point.

In the sentence, the speaker is implied to be female, so Greek uses the feminine direct object pronoun:

• την ακούω = I listen to her / I hear her

If the person speaking were male, it would be:

• τον ακούω = I listen to him / I hear him

So even though Ελλάδα is also feminine, την here does not mean Greece. It means her.

In Greek, object pronouns like με, σε, τον, την, το usually come before the verb.

So Greek says:

• την ακούω = literally her I-listen-to

This is normal Greek word order for clitic pronouns.

After να, the pronoun still comes before the verb:

• να την ακούω

This is about aspect, which is very important in Greek.

• ακούω = imperfective: ongoing, repeated, habitual
• ακούσω = perfective / aorist stem: one whole event, seen as complete

In this sentence:

• θέλω να την ακούω περισσότερο

suggests I want to listen to her more, meaning more often, for longer, or on a continuing basis.

If you said θέλω να την ακούσω, it would sound more like I want to listen to her / hear her in a more single-event sense.

So ακούω fits better with the idea of more and more / more often.

Here περισσότερο means more.

In this sentence it modifies the idea of listening:

• θέλω να την ακούω περισσότερο = I want to listen to her more

Depending on context, that can mean:

• more often
• for a longer time
• to a greater extent

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

The sentence as given is very natural:

• Μιλάει για την Ελλάδα με τόση αγάπη που θέλω να την ακούω περισσότερο.

But Greek can move parts around for emphasis. For example, με τόση αγάπη could sometimes be shifted, depending on style and focus.

What usually stays stable here is the core grammar:

• μιλάει για την Ελλάδα
• θέλω να την ακούω

So word order can move, but the original sentence is a very normal and natural version.
