Μου αρέσει ο τρυφερός τρόπος με τον οποίο η γιαγιά μου μιλάει στα παιδιά, και πραγματικά τη θαυμάζω γι’ αυτό.

In Greek, αρέσει works more like is pleasing than like English like.

So:

• Μου = to me
• αρέσει = it pleases / is pleasing

So Μου αρέσει ο τρυφερός τρόπος... is literally closer to:

• The tender way ... is pleasing to me

That is why Greek uses μου instead of a subject pronoun like εγώ here.

Because the thing being liked is singular: ο τρυφερός τρόπος = the tender way / manner.

With αρέσει / αρέσουν, the verb agrees with the thing that pleases you:

• Μου αρέσει ο τρόπος = I like the way ...
• Μου αρέσουν οι τρόποι = I like the ways / manners

Here, the subject is singular, so αρέσει is correct.

Because it is the grammatical subject of αρέσει.

Even though in English we say I like the tender way, Greek structures it differently:

• Μου = indirect object, to me
• ο τρυφερός τρόπος = subject, the tender way
• αρέσει = pleases

Since ο τρυφερός τρόπος is the subject, it appears in the nominative:

• ο = masculine singular nominative article
• τρυφερός = masculine singular nominative adjective
• τρόπος = masculine singular nominative noun

Τρυφερός means tender, gentle, or affectionate.

In this sentence, it describes the grandmother’s way of speaking to the children. So it suggests warmth, softness, kindness, and affection.

It agrees with τρόπος, so it is masculine singular:

• ο τρόπος
• ο τρυφερός τρόπος

It means the way in which or the way that.

This is a common Greek structure:

• ο τρόπος = the way / manner
• με τον οποίο = in which / by which / that

So:

• ο τρυφερός τρόπος με τον οποίο η γιαγιά μου μιλάει στα παιδιά = the tender way in which my grandmother speaks to the children

In more natural English, you would usually just say:

• the tender way my grandmother speaks to the children

Yes, it often could.

A more everyday version would be:

• Μου αρέσει ο τρυφερός τρόπος που η γιαγιά μου μιλάει στα παιδιά...

Using με τον οποίο is a bit more explicit and slightly more formal or careful in style.

So:

• που = very common, simpler
• με τον οποίο = more formal / more structured

Both are correct in the right context.

Because it refers back to τρόπος, which is:

• masculine
• singular

And because it comes after the preposition με, it must be in the accusative form:

• nominative: ο οποίος
• accusative: τον οποίο

So:

• με τον οποίο = by/in which

This whole phrase agrees with τρόπος.

Η γιαγιά μου is the normal way to say my grandmother.

Greek usually places the weak possessive pronoun after the noun:

• η μητέρα μου = my mother
• ο φίλος μου = my friend
• η γιαγιά μου = my grandmother

A different word order can happen for emphasis in some contexts, but η γιαγιά μου is the standard form.

Στα is the contraction of:

• σε + τα = στα

So:

• στα παιδιά = to the children

The verb μιλάω / μιλώ / μιλάω often takes σε when you mean speak to someone:

• Μιλάω στη μητέρα μου = I speak to my mother
• Μιλάει στα παιδιά = She speaks to the children

So here it does not mean with the children in the sense of mutual conversation; it means to the children.

Because after σε the noun appears in the accusative.

Here:

• τα παιδιά = nominative/accusative plural
• στα παιδιά = to the children

Παιδί is a neuter noun, and in the plural the nominative and accusative are the same:

• singular: το παιδί
• plural: τα παιδιά

So the form παιδιά is exactly what you expect after στα.

Πραγματικά means really or truly.

Here it emphasizes the speaker’s feeling:

• και πραγματικά τη θαυμάζω = and I really admire her

It can often move around in Greek without changing the basic meaning much:

• και πραγματικά τη θαυμάζω
• και τη θαυμάζω πραγματικά

Both are possible, though the nuance of emphasis may shift slightly.

Τη is the weak direct object pronoun meaning her.

So:

• θαυμάζω = I admire
• τη θαυμάζω = I admire her

It refers back to η γιαγιά μου.

Greek very often uses these unstressed object pronouns before the verb:

• τον βλέπω = I see him
• την αγαπώ = I love her
• τη θαυμάζω = I admire her

Before a consonant, την is often shortened in writing to τη:

• τη θαυμάζω

In Greek, once the person has already been mentioned, using the object pronoun is the normal way to continue.

So after mentioning η γιαγιά μου, Greek naturally says:

• τη θαυμάζω = I admire her

You would not normally repeat τη γιαγιά μου unless you wanted strong emphasis or contrast.

Γι’ αυτό means for that, because of that, or more naturally here, for that reason.

It refers to the whole previous idea: the tender way the grandmother speaks to the children.

So:

• και πραγματικά τη θαυμάζω γι’ αυτό = and I really admire her for that = and I truly admire her because of that

It does not refer to just one noun; it refers to the whole behavior described earlier.

Γι’ is a shortened form of για before a vowel.

So:

• για αυτό → γι’ αυτό

This contraction is very common and natural in writing.

You will also see similar contractions such as:

• απ’ όλα for από όλα
• σ’ εμένα for σε εμένα
• τ’ όνομα for το όνομα in certain styles

So γι’ αυτό is just the contracted form of για αυτό.

Both are possible in Modern Greek.

• μιλάει
• μιλά

Both mean he/she speaks.

So you could also say:

• η γιαγιά μου μιλά στα παιδιά

The longer forms like μιλάει are very common in everyday Greek and often sound a bit fuller or more colloquial, depending on the speaker and region.

The present tense here describes a general, repeated, or characteristic action.

• η γιαγιά μου μιλάει στα παιδιά does not necessarily mean she is speaking right now

It means something more like:

• the way my grandmother speaks to children
• the way she usually speaks to them
• her manner of speaking to them

Greek present tense often works like English present tense in this kind of general statement.

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

For example, parts of the sentence could move for emphasis:

• Πραγματικά τη θαυμάζω γι’ αυτό
• Τη θαυμάζω πραγματικά γι’ αυτό
• Γι’ αυτό πραγματικά τη θαυμάζω

These all mean roughly the same thing, but the emphasis changes.

Still, the original sentence sounds very natural and well-balanced.

It is mostly neutral to slightly careful/polished.

What makes it sound a bit more polished is especially:

• ο τρόπος με τον οποίο instead of simpler ο τρόπος που

The rest is very normal everyday Greek:

• Μου αρέσει...
• η γιαγιά μου μιλάει στα παιδιά
• τη θαυμάζω γι’ αυτό

So overall, it sounds natural, educated, and not overly formal.
