Sewe dae is een week.

Word by word:

• Sewe = seven
• dae = days
• is = is
• een = one
• week = week

So the sentence is a straightforward equation-style statement: Seven days is one week.

Because Afrikaans does not change the present tense of to be according to number the way English does.

In English, you say:

• One day is
• Two days are

In Afrikaans, you use is in both cases:

• Een dag is ...
• Twee dae is ...

So even though dae is plural, is is still correct.

Een means the number one.

'n means a / an.

In this sentence, the idea is mathematical or definitional: seven days = one week. Because the exact number matters, een is the natural choice.

Compare:

• een week = one week
• 'n week = a week

Both can refer to a singular week, but een stresses the number.

Because Afrikaans, like English, often uses bare plural nouns in general statements.

So:

• Sewe dae = seven days

You do not need die or 'n there.

That is similar to English:

• Seven days is one week
• not The seven days is one week in this meaning

The sentence is talking about a quantity, not a specific set of days.

Because dag has an irregular-looking plural:

• dag = day
• dae = days

This is something you mainly learn as vocabulary. It is not formed by simply adding -s.

Many Afrikaans plurals do use patterns like -e or -s, but some common words change internally as well. dag → dae is one of those forms you should memorize.

Yes, in this sentence it is very close to English.

Structure:

• Sewe dae = subject
• is = verb
• een week = complement

So Afrikaans and English line up neatly here:

• Seven days is one week
• Sewe dae is een week

This makes the sentence especially easy for an English speaker to recognize.

It is correct and easy to understand, especially as a definition or a fact.

But in everyday speech, many speakers would more naturally say:

• Daar is sewe dae in 'n week. = There are seven days in a week.

So:

• Sewe dae is een week sounds a bit like an equation or textbook statement.
• Daar is sewe dae in 'n week sounds more conversational.

Yes. That is also correct.

It simply flips the two sides of the statement:

• Sewe dae is een week
• Een week is sewe dae

Both mean the same thing. The difference is just which side you present first.

A rough learner-friendly guide is:

• Sewe ≈ SEH-vuh
• dae ≈ dye
• is ≈ iss
• een ≈ ee-un or a quick een
• week starts with a v-like sound, not an English w

A very rough full approximation:

SEH-vuh dye iss ee-un veek

Two useful pronunciation notes:

• Afrikaans w usually sounds more like English v
• Afrikaans ee is not exactly the same as English ee, so listen to native audio if you can

No. In a sentence like this, sewe stays sewe.

Afrikaans numbers generally do not change form to agree with nouns. So you can say:

• sewe dae = seven days
• sewe weke = seven weeks
• sewe boeke = seven books

The number itself stays the same.

Because it follows een, which means one.

So:

• een week = one week
• twee weke = two weeks

Since the quantity is one, the noun stays singular.

The plural is:

• week = week
• weke = weeks

So you could say:

• een week = one week
• twee weke = two weeks

That helps show the contrast with dag → dae, which is less regular-looking.
