Η μικρή δεν έσπασε το ποτήρι επίτηδες, γι’ αυτό δεν θυμώσαμε.

In Greek, adjectives can be used on their own as nouns when the noun is understood from context.

So η μικρή literally means the small one, but in normal usage it often means:

• the little girl
• the younger one
• the child
• sometimes even my daughter, depending on context

Here:

• η = feminine singular definite article
• μικρή = feminine singular form of μικρός (small / little)

Because it is feminine, the listener understands that it refers to a female person.

Because adjectives in Greek must agree with the noun they describe—or with the implied noun if the adjective is used by itself.

The forms of μικρός are:

• μικρός = masculine
• μικρή = feminine
• μικρό = neuter

Since η μικρή refers to a feminine person, the feminine form μικρή is required.

Δεν is the standard word for not before verbs in modern Greek.

So:

• δεν έσπασε = did not break
• δεν θυμώσαμε = we did not get angry

It comes directly before the verb (or before the verb phrase).

Έσπασε is the aorist form of σπάζω (to break).
The Greek aorist usually corresponds to the English simple past for a completed action.

So:

• σπάζω = I break / I am breaking
• έσπασε = she/he/it broke

In this sentence, it refers to one completed event: the glass got broken.

Greek often omits subject pronouns because the verb ending usually shows the person and number.

Here, έσπασε can mean:

• he broke
• she broke
• it broke

The subject is understood from context: η μικρή.

So Greek does not need to say she separately.

Το ποτήρι means the glass and it is the direct object of the verb έσπασε, so it is in the accusative case.

However, with many neuter nouns, the nominative and accusative forms are the same.

For ποτήρι:

• nominative: το ποτήρι
• accusative: το ποτήρι

So even though it is accusative here, it looks the same as the dictionary/basic form.

Επίτηδες means on purpose, deliberately, or intentionally.

So:

• δεν έσπασε το ποτήρι επίτηδες = she didn’t break the glass on purpose

It is a very common word when talking about intention.

Examples:

• Το έκανα επίτηδες. = I did it on purpose.
• Δεν το είπε επίτηδες. = He/She didn’t say it deliberately.

Greek word order is more flexible than English.
Επίτηδες often comes after the verb and object, especially in everyday speech.

So this order is very natural:

• δεν έσπασε το ποτήρι επίτηδες

It could also be moved for emphasis in other contexts, but the version in your sentence sounds normal and idiomatic.

Γι’ αυτό is the usual contracted form of για αυτό and means for that, which in this context is best translated as:

• that’s why
• for that reason
• so

In this sentence:

• γι’ αυτό δεν θυμώσαμε = that’s why we didn’t get angry

The apostrophe shows that a vowel has dropped:

• για αυτό → γι’ αυτό

This contracted form is extremely common in writing.

Θυμώσαμε is the aorist of θυμώνω (to get angry).

It means:

• we got angry
• in this negative sentence: we didn’t get angry

Form breakdown:

• θυμώνω = I get angry / I am getting angry
• θυμώσαμε = we got angry

So the sentence refers to a completed reaction in the past.

Because θυμώνω focuses on becoming angry rather than simply being angry.

So:

• θυμώσαμε = we got angry
• δεν θυμώσαμε = we didn’t get angry

If you wanted to say we weren’t angry, Greek might use a different structure, such as one based on the adjective θυμωμένοι (angry) depending on context.

Here, the idea is about the reaction: they did not become angry because it was not intentional.

It introduces the result or consequence of what came before.

Structure:

• Η μικρή δεν έσπασε το ποτήρι επίτηδες = The little girl didn’t break the glass on purpose
• γι’ αυτό δεν θυμώσαμε = that’s why we didn’t get angry

So the logic is:

1. It was not intentional.
2. Therefore, we did not get angry.

This is a very common Greek way to link cause and result.

It sounds quite natural and conversational, but it is also perfectly standard Greek.

A few features that make it feel natural:

• η μικρή instead of repeating a full noun like το κορίτσι
• επίτηδες for on purpose
• γι’ αυτό as a common spoken and written connector

So it is a good example of everyday standard Greek.
