Die karton is droog.

Die is the Afrikaans definite article, so it usually means the.

A few useful things about die:

• It is used for all nouns.
• Afrikaans does not have grammatical gender like German.
• It does not change for case.
• So die can mean the regardless of whether the noun is masculine, feminine, neuter, singular, or plural.

In Die karton is droog, die karton = the cardboard / the carton.

Because Afrikaans and English are related Germanic languages, and some very common words look similar.

In Afrikaans, is is the present-tense form of to be, and it is used very widely. One helpful feature is that Afrikaans verbs do not conjugate the way English verbs do.

So you get:

• Ek is = I am
• Jy is = you are
• Hy/Sy is = he/she is
• Ons is = we are
• Hulle is = they are

So in this sentence, is simply means is.

This is the normal word order for a simple main clause in Afrikaans:

subject + verb + complement

So here:

• Die karton = subject
• is = verb
• droog = complement/adjective

This is very similar to English:

• The cardboard is dry.

Afrikaans is a verb-second language in main clauses, which means the finite verb typically comes in the second position. In this sentence, the subject comes first, so the verb follows it naturally.

Because here droog is being used after the verb is, so it is a predicative adjective.

Predicative adjectives in Afrikaans usually stay in their basic form:

• Die karton is droog. = The cardboard is dry.
• Die gras is groen. = The grass is green.

If the adjective comes before the noun, it often changes form:

• die droë karton = the dry cardboard

So:

• is droog = is dry
• die droë karton = the dry cardboard

That difference is very common in Afrikaans.

This is one of the patterns learners often notice.

Afrikaans adjectives can have:

• a basic form when used after a verb: droog
• an attributive form when used before a noun: droë

So:

• Die karton is droog.
• die droë karton

The change from droog to droë is part of how that adjective behaves in attributive position. Not every adjective changes in exactly the same visual way, so it is something you gradually get used to.

A rough guide:

• droog sounds approximately like drohkh or drawkh, depending on accent
• the oo is a long vowel
• the final g is the important part: in Afrikaans it is usually a harsh throaty sound, not an English g as in go

So do not pronounce it like English drog with a normal hard g.

A very rough English-friendly approximation is:

• drohkh

But the real Afrikaans g is made farther back in the throat.

A rough pronunciation is:

• kar-TON

The stress is usually on the second syllable.

A simple approximation for English speakers:

• kar-TAWN or kar-TON

The r is Afrikaans-style, and the vowels may be a bit different from English depending on accent, but the main thing is that the second syllable is stressed.

Not always exactly.

In Afrikaans, karton often refers to cardboard or carton-type material/packaging, depending on context. So it can overlap with English cardboard and carton.

That is why context matters. In one sentence it may be best translated as:

• the cardboard is dry

and in another context it could refer more to a carton or box-like packaging.

Yes. That would mean The cardboard is wet.

This is a useful comparison because the structure is exactly the same:

• Die karton is droog. = The cardboard is dry.
• Die karton is nat. = The cardboard is wet.

This helps show that is + adjective works much like English.

Yes. A yes/no question is usually made by putting the verb first:

• Is die karton droog? = Is the cardboard dry?

That is a very common Afrikaans pattern.

Compare:

• Statement: Die karton is droog.
• Question: Is die karton droog?

Not as a normal main-clause statement.

For a simple statement, you would say:

• Die karton is droog.

But droog is can appear at the end in a subordinate clause, for example after dat:

• Ek weet dat die karton droog is. = I know that the cardboard is dry.

So:

• main clause: Die karton is droog
• subordinate clause: dat die karton droog is

That word-order difference is an important feature of Afrikaans.

No, not in this sentence.

You already have the definite article die, meaning the:

• Die karton = the cardboard / the carton

If you wanted to say a carton or a piece of cardboard, you might use ’n in a different sentence:

• ’n Karton is droog. = A carton is dry.

So in your original sentence, die is already doing the article job.
