Η γιαγιά μου διηγείται με τόσο τρυφερό τρόπο τα ίδια παραμύθια, που τα παιδιά θέλουν να τα ακούνε κάθε βράδυ.

μου here is the unstressed possessive pronoun, meaning my.

So:

• η γιαγιά = the grandmother
• η γιαγιά μου = my grandmother

In Greek, these short possessive forms usually come after the noun:

• το βιβλίο μου = my book
• η μητέρα μου = my mother
• οι φίλοι μου = my friends

This is much more natural than trying to copy English word order.

Greek normally uses the definite article with possessive expressions.

So Greek says:

• η γιαγιά μου literally = the grandmother my

but naturally it means:

• my grandmother

This is standard Greek usage, not something special about this sentence.

διηγείται is the 3rd person singular present form of διηγούμαι, which means to narrate / tell a story.

So:

• διηγούμαι = I tell / narrate
• διηγείται = he/she tells / narrates

Even though the ending looks like a passive or middle form, διηγούμαι is a very common verb that is used this way with an active meaning. Learners often meet verbs like this in Greek.

In this sentence:

• Η γιαγιά μου διηγείται... = My grandmother tells...

Because the dictionary form of the verb is διηγούμαι, not an active-form verb like γράφω or λέω.

Many Greek verbs are conjugated in the middle/passive set of endings but still have an active meaning. These are often called deponent-like verbs in learner explanations.

So you do not say:

• διηγεί ❌

You say:

• διηγείται ✔

The learner just needs to remember διηγούμαι as the normal verb for tell/narrate a story.

Literally, it means:

• με = with
• τόσο = such / so
• τρυφερό = tender
• τρόπο = way, manner

So the whole phrase is:

• with such a tender way/manner

Natural English would usually say:

• in such a tender way
• so tenderly

Greek often uses με + noun to express manner:

• με προσοχή = carefully
• με χαρά = with joy
• με όμορφο τρόπο = in a beautiful way

So this phrase is a very natural Greek way to describe how she tells the stories.

Yes, it could.

• διηγείται με τόσο τρυφερό τρόπο = she tells them in such a tender way
• διηγείται τόσο τρυφερά = she tells them so tenderly

The version in your sentence is a bit more descriptive and slightly more expressive. Greek often prefers a noun phrase like με ... τρόπο when it wants a fuller, more vivid style.

ίδια here means same.

So:

• τα παραμύθια = the fairy tales
• τα ίδια παραμύθια = the same fairy tales

The adjective ίδιος, ίδια, ίδιο agrees with the noun in gender, number, and case.

Since παραμύθια is:

• neuter
• plural
• accusative here

the form is:

• ίδια

That is why you get:

• τα ίδια παραμύθια

Because τόσο ... που forms a result structure:

• τόσο ... που ... = so/such ... that ...

Here the pattern is:

• με τόσο τρυφερό τρόπο ... που τα παιδιά θέλουν...
• in such a tender way ... that the children want...

So που is introducing the result of the grandmother’s storytelling.

The comma helps separate the main part from the result clause, just like English often separates such ... that clauses clearly.

Here που means that in the sense of introducing a result clause.

It is not a relative pronoun here.

Compare:

• Έχει τόσο ωραία φωνή, που όλοι τη θυμούνται. = She has such a beautiful voice that everyone remembers it.

But in another sentence, που can also act like who/that/which:

• Το παιδί που γελάει = the child who is laughing

So the function of που depends on context. In your sentence, it is clearly result: so/such ... that.

Because this τα is not the article. It is a direct object pronoun meaning them.

So:

• τα ίδια παραμύθια = the same fairy tales
• να τα ακούνε = to listen to them

This pronoun refers back to παραμύθια.

Greek often repeats the object with a clitic pronoun, especially when the object has already been mentioned and is then referred to again.

So the two τα are different:

• first τα = the
• second τα = them

This is a very important aspect question.

After θέλουν να, Greek can use either:

• imperfective form: ακούνε
• perfective form: ακούσουν

The difference is about how the action is viewed.

In this sentence:

• θέλουν να τα ακούνε κάθε βράδυ

This suggests a repeated, habitual action:

• they want to listen to them again and again
• every night

So the imperfective form ακούνε fits very well.

If you said να τα ακούσουν:

That would sound more like:

• they want to hear them
• perhaps as a more complete, one-time event

Because the sentence includes κάθε βράδυ, the imperfective ακούνε is especially natural.

In form, it looks like a present-tense form, but after να it functions as a subjunctive construction.

So:

• ακούνε by itself can mean they hear / they are listening
• να ακούνε means something like to be listening / to listen repeatedly

In Modern Greek, after να, the form used is not described the same way English describes infinitives. Greek does not normally use an infinitive here. Instead, it uses να + verb form.

So:

• θέλουν να τα ακούνε = they want to listen to them

Because Modern Greek generally does not use an infinitive the way English does.

English says:

• they want to hear them

Greek says:

• θέλουν να τα ακούνε

The pattern is:

• θέλω να + verb

Examples:

• Θέλω να φύγω = I want to leave
• Θέλουμε να μάθουμε = we want to learn
• Τα παιδιά θέλουν να τα ακούνε = the children want to listen to them

So να is a basic and extremely important part of Greek grammar.

Because τα παιδιά is grammatically plural.

Even though παιδιά is neuter, it still takes a plural verb:

• το παιδί θέλει = the child wants
• τα παιδιά θέλουν = the children want

So the verb agrees with the subject in number.

Here παιδιά is in the nominative plural, because it is the subject of the second clause:

• τα παιδιά θέλουν... = the children want...

The form παιδιά is the same in nominative and accusative plural, so the case is understood from its role in the sentence.

Because κάθε means each / every, and Greek normally does not add the definite article after it in expressions like this.

So:

• κάθε μέρα = every day
• κάθε βράδυ = every night
• κάθε χρόνο = every year

This is just the normal pattern.

παραμύθι usually means fairy tale, folk tale, or a story of that kind, especially one told to children.

So in this sentence, παραμύθια strongly suggests bedtime stories/fairy tales rather than just any stories.

A more general word for stories is often:

• ιστορίες

So:

• παραμύθια = fairy tales / tales
• ιστορίες = stories

Greek word order is fairly flexible, although some choices sound more natural than others.

This sentence is very natural as written:

• Η γιαγιά μου διηγείται με τόσο τρυφερό τρόπο τα ίδια παραμύθια, που...

But Greek could move elements for emphasis. For example, you might hear:

• Η γιαγιά μου τα ίδια παραμύθια διηγείται...
• Με τόσο τρυφερό τρόπο διηγείται η γιαγιά μου...

These versions change the focus or emphasis, not the basic meaning.

The original sentence is a smooth, neutral way to say it.

The sentence follows this structure:

• Main clause:
  Η γιαγιά μου διηγείται με τόσο τρυφερό τρόπο τα ίδια παραμύθια
• Result clause:
  που τα παιδιά θέλουν να τα ακούνε κάθε βράδυ

So the full pattern is:

• τόσο + phrase + που
• so/such + phrase + that

A simple model would be:

• Μιλάει τόσο γλυκά, που όλοι τον αγαπούν. = He speaks so sweetly that everyone loves him.

Your sentence uses exactly this kind of structure.
