Η σαμπάνια είναι κρύα.

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

Because σαμπάνια is a feminine singular noun, it takes η:

• η σαμπάνια = the champagne

In Greek, the article changes for gender, number, and case, unlike English the, which always stays the same.

In Greek, every noun has a grammatical gender: masculine, feminine, or neuter. Σαμπάνια is treated as a feminine noun, so words that go with it must match that gender.

That is why you get:

• η σαμπάνια
• κρύα and not κρύο or κρύος

This is grammatical gender, so it is just part of how the noun behaves in Greek.

Because adjectives in Greek usually agree with the noun they describe in gender, number, and case.

Since σαμπάνια is:

• feminine
• singular
• nominative

the adjective must also be feminine singular nominative:

• masculine: κρύος
• feminine: κρύα
• neuter: κρύο

So:

• Η σαμπάνια είναι κρύα. = The champagne is cold.

Είναι means is here.

It is the present-tense form of to be used with he/she/it and also they:

• είναι = is / are

In this sentence, the subject is singular:

• Η σαμπάνια είναι κρύα.
• The champagne is cold.

Greek often drops subject pronouns, but the verb is still there. Since the noun η σαμπάνια is already the subject, there is no need for a separate word for it.

A simple pronunciation guide is:

ee sam-BA-nya EE-ne KRY-a

More roughly:

• Η = ee
• σαμπάνια = sam-BA-nya
• είναι = EE-ne
• κρύα = KRY-a

A few useful notes:

• μπ in a word like σαμπάνια is pronounced like b
• νια sounds like nya
• υ in κρύα sounds like ee in Modern Greek, so κρύα is not pronounced like English cryo
• The accent marks show which syllable gets the stress:
  • σαμπάνια
  • είναι
  • κρύα

Greek uses accent marks to show which syllable is stressed.

So in this sentence:

• είναι → stress on the first syllable
• κρύα → stress on the first syllable
• σαμπάνια → stress on πά

This helps both with pronunciation and with correct spelling. In Greek, accent placement matters, so learners should pay attention to it from the beginning.

Yes. Greek word order is more flexible than English word order.

The most neutral order here is:

• Η σαμπάνια είναι κρύα.

But other orders are possible for emphasis, for example:

• Κρύα είναι η σαμπάνια. = The champagne is cold.
  This can sound more emphatic, like contrasting it with something else.

Even though the order can change, beginners should usually start with the standard pattern:

• subject + verb + adjective

Because κρύα is a predicate adjective here, not a noun phrase.

In Η σαμπάνια είναι κρύα, the structure is:

• η σαμπάνια = subject
• είναι = linking verb
• κρύα = adjective describing the subject

In English we also say the champagne is cold, not the champagne is the cold. Greek works similarly here.

Usually, in a simple sentence like this, η sounds more natural.

• Η σαμπάνια είναι κρύα. = The champagne is cold.

If you remove the article, the sentence may sound unnatural or incomplete in many contexts. Greek often uses the definite article more broadly than English does.

So for a learner, the safest version is:

• Η σαμπάνια είναι κρύα.

Yes, it is a loanword corresponding to champagne.

Its Greek form is:

• σαμπάνια

Like many borrowed nouns in Greek, it has been adapted to Greek spelling and grammar. Even though the word comes from another language, in Greek it behaves like a normal feminine noun.

In this sentence, it clearly means physically cold because it refers to champagne.

Greek κρύος / κρύα / κρύο can also describe people in a more figurative sense, depending on context, much like English cold.

But here there is no ambiguity:

• Η σαμπάνια είναι κρύα. = the drink is cold

A Greek speaker can absolutely say:

• Η σαμπάνια είναι κρύα.

That means the champagne is cold.

You might also hear:

• Η σαμπάνια είναι παγωμένη.

That means something more like ice-cold, very chilled, or frozen/chilled through, depending on context.

So:

• κρύα = cold
• παγωμένη = very cold / chilled / ice-cold

Both are natural, but κρύα is the straightforward basic word.

It can mean both is and are.

Greek είναι is used for:

• he is
• she is
• it is
• they are

So the exact English translation depends on the subject.

Examples:

• Η σαμπάνια είναι κρύα. = The champagne is cold.
• Οι σαμπάνιες είναι κρύες. = The champagnes are cold.

The form είναι stays the same, but the subject tells you whether it is singular or plural.
