Ek werk sewe dae.

In Afrikaans, present-tense verbs usually do not change form for different subjects.

So you get:

• ek werk = I work
• jy werk = you work
• hy werk = he works
• ons werk = we work

This is simpler than English, where you have I work but he works.

Yes. It is in the present tense.

Depending on context, the present tense in Afrikaans can cover ideas like:

• a general fact or habit
• a current situation
• sometimes a planned or understood situation

So the exact English translation can depend on context, even though the Afrikaans verb form stays the same.

Afrikaans often expresses duration with just number + time word.

So sewe dae can simply mean for seven days or seven days, depending on context.

That is why Ek werk sewe dae is normal Afrikaans.

You may also hear forms like:

• vir sewe dae
• sewe dae lank

These make the duration a bit more explicit, but they are not required here.

Because sewe is more than one, the noun has to be plural.

• dag = day
• dae = days

The plural of dag is irregular enough that it is best learned as a set: dag / dae.

After a number, Afrikaans normally uses the noun directly.

So you say:

• een dag = one day
• twee dae = two days
• sewe dae = seven days

You do not add 'n before the noun in this kind of phrase.

The sentence follows the normal basic order for a simple statement:

• Ek = subject
• werk = verb
• sewe dae = time/duration phrase

So the pattern is:

subject + verb + rest

This is the most natural order for a simple main clause like this one.

By itself, it simply says I work seven days, so context matters.

If you want to be more specific, Afrikaans often adds extra words:

• sewe dae lank = for seven days / seven days in a row
• sewe dae per week = seven days a week

So the bare sentence is understandable, but a fuller version may be used if the speaker wants to remove ambiguity.

A rough English-friendly guide is:

• Ek ≈ eck
• werk ≈ verk
• sewe ≈ SEH-vuh
• dae ≈ dye

So the whole sentence sounds roughly like:

eck verk SEH-vuh dye

One useful point: Afrikaans w is usually pronounced more like an English v.
