Το έπιπλο είναι ογκώδες.

• Το = the
• έπιπλο = piece of furniture / furniture item
• είναι = is
• ογκώδες = bulky, cumbersome, voluminous

So the structure is very straightforward: article + noun + is + adjective.

Because έπιπλο is a neuter singular noun in Greek. The definite article must match the noun’s gender, number, and case.

Here, το is the neuter singular nominative form of the.

Greek articles change form:

• ο for many masculine nouns
• η for many feminine nouns
• το for many neuter nouns

Since έπιπλο is neuter, Greek uses το.

No. In Greek, grammatical gender is a grammar category, not a statement about real-world sex or gender.

Έπιπλο is simply a noun that belongs to the neuter gender class. Many Greek nouns ending in -ο are neuter, and έπιπλο follows that common pattern.

This matters because other words around it must agree with it, such as:

• the article: το
• the adjective: ογκώδες

Because the adjective has to agree with έπιπλο.

Since έπιπλο is neuter singular, the adjective also appears in its neuter singular form: ογκώδες.

This adjective has forms like:

• masculine/feminine singular: ογκώδης
• neuter singular: ογκώδες

So:

• Ο καναπές είναι ογκώδης. = The sofa is bulky.
• Η ντουλάπα είναι ογκώδης. = The wardrobe is bulky.
• Το έπιπλο είναι ογκώδες. = The piece of furniture is bulky.

Because ογκώδες is being used as a predicate adjective, not an adjective directly attached before the noun.

In Το έπιπλο είναι ογκώδες, the pattern is: The furniture item + is + bulky

After είναι, Greek normally uses the adjective without an article.

Compare:

• Το έπιπλο είναι ογκώδες. = The piece of furniture is bulky.
• Το ογκώδες έπιπλο = The bulky piece of furniture

The second one is an adjective directly modifying the noun. The first one is a full sentence.

In the singular, έπιπλο usually means a piece of furniture or an item of furniture.

That is different from English, where furniture is usually uncountable.

So:

• ένα έπιπλο = a piece of furniture
• τα έπιπλα can mean the furniture or the pieces of furniture, depending on context

This is a very common difference between Greek and English.

A rough English-friendly pronunciation is:

to EH-pee-plo EE-ne ong-GO-thes

A few notes:

• έπιπλο has the stress on the first syllable: EH-pee-plo
• είναι is pronounced EE-ne
• ογκώδες has the stress on -κώ-: ong-GO-thes
• the δ in ογκώδες sounds like th in this, not th in think

Also, the accent marks show you where the stress goes:

• έπιπλο
• είναι
• ογκώδες

Normally, no. In standard Greek, you usually keep είναι in sentences like this.

So the normal sentence is: Το έπιπλο είναι ογκώδες.

Leaving it out would sound incomplete in ordinary speech, except in special styles such as notes, headlines, or very elliptical language.

English learners sometimes expect Greek to allow The furniture bulky-type structures, but standard Greek generally does not.

Yes, Greek word order is more flexible than English, but the original order is the most neutral and natural here.

Neutral: Το έπιπλο είναι ογκώδες.

For emphasis, you might also hear: Ογκώδες είναι το έπιπλο.

That version puts focus on ογκώδες. It can sound contrastive, as if you are emphasizing that the furniture is specifically bulky.

Still, for a learner, the safest default is the original sentence order.

You would say:

Τα έπιπλα είναι ογκώδη.

Changes:

• το → τα
• έπιπλο → έπιπλα
• ογκώδες → ογκώδη

Notice something important:
είναι stays είναι in both he/she/it is and they are in the present tense.

So:

• Το έπιπλο είναι ογκώδες. = The piece of furniture is bulky.
• Τα έπιπλα είναι ογκώδη. = The pieces of furniture are bulky.

Not exactly.

Ογκώδες usually means something more like:

• bulky
• cumbersome
• taking up a lot of space
• large in volume

It suggests not just size, but also mass or awkward bulk.

If you only want to say big or large, Greek often uses μεγάλο instead:

• Το έπιπλο είναι μεγάλο. = The piece of furniture is big.

So ογκώδες is more specific than just large.
