Η διασκέδαση ήταν καλή.

A natural pronunciation is:

ee thee-ah-SKEH-tha-see EE-tan ka-LEE

A few notes:

• Η = ee
• διασκέδαση has the stress on σκέ
• ήταν has the stress on ή
• καλή has the stress on the last syllable

Also, Greek δ sounds like the th in this, not like the English d.

Η is the feminine singular definite article, so it means the.

In this sentence:

• Η διασκέδαση = the fun / the entertainment

Greek uses articles much more regularly than English, so where English might sometimes omit the, Greek often keeps it.

Because διασκέδαση is a feminine noun in Greek. Nouns in Greek have grammatical gender: masculine, feminine, or neuter.

You usually just have to learn the noun together with its article:

• η διασκέδαση = feminine

This gender then affects the form of adjectives used with it.

Because adjectives in Greek must agree with the noun they describe in:

• gender
• number
• case

Since διασκέδαση is feminine singular, the adjective also has to be feminine singular:

• masculine: καλός
• feminine: καλή
• neuter: καλό

So:

• η διασκέδαση ήταν καλή

is correct because both the noun and adjective are feminine singular.

Ήταν means was here.

It is the past-tense form of είμαι = to be.

So:

• είναι = is
• ήταν = was

In this sentence:

• Η διασκέδαση ήταν καλή = The fun was good

It is the imperfect past form of είμαι.

For είμαι, ήταν is the normal past form used for was and were in many contexts.

So even though grammatically it belongs to the imperfect system, in simple sentences like this you can think of it as the usual Greek way to say was.

Yes. Ήταν already contains the meaning of was.

Greek verbs usually include the subject information inside the verb form, so you do not need an extra helper word.

For example:

• ήταν = he/she/it was or they were, depending on context

Here the subject is clearly singular:

• η διασκέδαση = singular

So the meaning is was, not were.

The main noun διασκέδαση is in the nominative, because it is the subject of the sentence.

The adjective καλή is also in the nominative, because it is a predicate adjective after the verb ήταν and agrees with the subject.

So:

• Η διασκέδαση = nominative subject
• καλή = nominative adjective agreeing with the subject

No, Greek word order is more flexible than English.

The neutral order here is:

• Η διασκέδαση ήταν καλή.

But you could also say:

• Καλή ήταν η διασκέδαση.

That changes the emphasis slightly, almost like:

• The fun was good
• The fun was good, actually
• It was the fun that was good

So the original order is the most straightforward and neutral.

That is partly because they are both feminine singular forms, but they are not the same kind of word.

• διασκέδαση is a noun
• καλή is an adjective

Many feminine singular Greek words end in -η, but the ending alone does not tell you everything. You still need to know whether the word is a noun or adjective and what pattern it follows.

Yes, they matter because they show which syllable is stressed.

In this sentence:

• διασκέδαση → stress on σκέ
• ήταν → stress on ή
• καλή → stress on λή

Stress is important in Greek pronunciation, and sometimes changing the stress can make a word sound wrong or even change meaning in other cases.

In normal Greek, that would sound unnatural.

Greek usually wants the article here, especially with the subject of a sentence:

• Η διασκέδαση ήταν καλή.

Leaving out the article is much less natural than in English. English sometimes says things like Fun was good, but Greek normally would not do that here.

Not always exactly. Διασκέδαση can mean things like:

• fun
• entertainment
• amusement
• enjoyment

The exact English translation depends on context.

So in this sentence, if the meaning shown to the learner is The fun was good, that works, but in another context it could be understood more like The entertainment was good.

It is grammatically correct, but depending on context, Greek speakers might often choose a different expression.

For example:

• Η διασκέδαση ήταν ωραία. = The fun/entertainment was nice
• Περάσαμε καλά. = We had a good time

So Η διασκέδαση ήταν καλή is correct and understandable, but in everyday speech another phrasing may sometimes sound more natural.

Yes. Ήταν can be used for both:

• he/she/it was
• they were

The context tells you which one is meant.

Here the subject is singular:

• η διασκέδαση

So it clearly means:

• was

In the present tense, it would be:

• Η διασκέδαση είναι καλή.

That means:

• The fun is good
• The entertainment is good

So the change is:

• ήταν = was
• είναι = is

A very useful pattern is:

• [article + noun] + ήταν + [matching adjective]

For example:

• Η ταινία ήταν καλή. = The movie was good.
• Η μουσική ήταν ωραία. = The music was nice.
• Το φαγητό ήταν καλό. = The food was good.

This helps you practice:

• noun gender
• adjective agreement
• the past form ήταν
