De beer is groot.

Because beer is a de-word in Dutch. Dutch nouns have two article types in the singular:

• de for common gender nouns
• het for neuter nouns

So you say:

• de beer
• not het beer

Unfortunately, whether a noun takes de or het often has to be learned word by word.

A useful extra note:

• the diminutive would be het beertje (the little bear), because diminutives are always het words.

Dutch beer is pronounced roughly like English bear, but with a longer vowel.

A rough guide:

• beer ≈ bayr / bear
• IPA: /beːr/

Important:

• It is not pronounced like English beer (the drink).
• The r may sound different depending on region.

So although it is spelled like the English drink word, it sounds much closer to bear.

Because groot is being used after the verb is. In that position, Dutch adjectives normally stay in their basic form.

Compare:

• De beer is groot. → adjective after is → groot
• De grote beer → adjective before the noun → grote

This is a very common pattern in Dutch:

• Het huis is groot.
• Het grote huis.

So:

• after a linking verb like is: usually groot
• before a noun: often grote

Yes, in this simple main clause it is very similar to English.

The structure is:

• De beer = subject
• is = verb
• groot = adjective/complement

So the pattern is:

subject + verb + adjective

This is one reason sentences like this often feel familiar to English speakers.

Is is the third-person singular form of the verb zijn (to be).

So:

• ik ben = I am
• jij bent = you are
• hij/zij/het is = he/she/it is

In De beer is groot, is means is just like in English.

It can often do either, depending on context.

It may refer to:

• a specific bear already known in the conversation
• the bear as a type/animal in general, in some contexts

Dutch often uses the definite article in ways that may feel a little broader than English.

For example, depending on context, De beer is groot could mean:

• a particular bear is big
• the bear, as an animal, is big

Usually the surrounding context tells you which meaning is intended.

Yes, but it changes the meaning.

• De beer is groot = the bear is big
• Een beer is groot = a bear is big

So de points to something definite/specific, while een is indefinite.

Also note:

• een is pronounced differently from the number één
• een as an article usually sounds unstressed

No. In Dutch, common nouns are not capitalized.

So you write:

• de beer is groot

not:

• De Beer Is Groot

Only the first word of the sentence is capitalized here because it begins the sentence.

The plural would be:

De beren zijn groot.

Changes:

• beer → beren = bears
• is → zijn = are
• groot stays groot

So:

• singular: De beer is groot.
• plural: De beren zijn groot.

This is useful because it shows that Dutch adjectives after zijn/is still usually do not take an ending.

In the plural, Dutch nouns take de, not het.

So even if a singular noun is a het-word, its plural uses de.

For this noun:

• singular: de beer
• plural: de beren

This is a good general rule:

• all plural nouns use de

In neutral speech, the article de is usually unstressed.

A natural rhythm is roughly:

de BEER is GROOT

Often:

• de is weak: duh
• beer and groot carry more stress, depending on what is important

If someone is simply describing the bear, groot may get the strongest stress.

Yes. They are cognates, meaning they come from the same older Germanic source.

That is why they look and sound somewhat similar:

• Dutch: beer
• English: bear

This can make the word easier to remember, even though the spelling may trick English speakers at first.
