Sy steek die soom vas.

Here sy means she.

Afrikaans does not capitalize pronouns like English does with I. So sy is normally written lowercase unless it starts a sentence, as it does here.

One thing that often confuses learners: sy can also mean his in other sentences.
So context matters:

• Sy steek die soom vas. = She fastens the hem.
• sy jas = his coat

die is the definite article, meaning the.

So:

• die soom = the hem

Unlike English, Afrikaans uses die for basically all nouns in the definite form. It does not change for gender, and you do not need separate forms like the for masculine/feminine/neuter.

Soom means hem, especially the folded edge of a piece of clothing or fabric.

So in this sentence, it refers to the hem of a garment that is being fixed, sewn, pinned, or fastened.

Yes — steek is a very flexible verb in Afrikaans and can have several meanings depending on context.

Common meanings include:

• stick / put into
• stab
• sew / stitch
• pin / fasten

In Sy steek die soom vas, the meaning is not the violent sense stab. Here it is something like:

• fasten
• stitch down
• pin in place

So the exact English translation depends on context, but the clothing/sewing context makes the meaning clear.

Vas usually means something like:

• fast
• firm
• fixed
• securely
• stuck

In this sentence, vas adds the idea that the hem is being secured or fixed in place.

So steek ... vas is more than just put/stitch — it means fasten securely, stitch down, or pin down.

This is a very common Afrikaans pattern. The verb here is effectively a separable verb: vassteek.

• Dictionary / infinitive form: vassteek
• Main-clause form: steek ... vas

So in a normal statement, the conjugated part goes earlier in the sentence, and the separable part goes to the end:

• Sy steek die soom vas.

This is similar to how separable verbs work in Dutch and a bit like some particle verbs in English, such as put on or write down, though Afrikaans uses the pattern much more systematically.

No, not in a normal main clause.

In a main clause, Afrikaans usually places the finite verb in the second position, and with separable verbs the particle goes to the end:

• Sy steek die soom vas. ✅

The combined form vassteek appears in places like the infinitive or where the verb is not split, for example in dictionary form:

• om die soom vas te steek = to fasten the hem

So:

• main clause: steek ... vas
• infinitive: vas te steek

Afrikaans verbs are much simpler than English verbs in this way. They usually do not change according to the subject.

So you get:

• Ek steek
• Jy steek
• Sy steek
• Ons steek
• Hulle steek

The verb stays steek.
That is one of the biggest simplifications in Afrikaans grammar compared with English and many other European languages.

Yes, as written, it is in the present tense:

• Sy steek die soom vas. = She fastens / is fastening the hem.

Afrikaans present tense can often cover both simple present and present progressive, depending on context.

If you want the past, Afrikaans commonly uses het + past participle:

• Sy het die soom vasgesteek. = She fastened / has fastened the hem.

For future:

• Sy sal die soom vassteek. = She will fasten the hem.

It could be either, depending on context.

Because steek is broad, the phrase can suggest:

• sewing the hem down
• pinning the hem in place
• fastening it securely

If the surrounding context is about tailoring or using a needle and thread, it will often be understood as sewing or stitching. If the context involves pins, it may mean pinning. So the exact nuance comes from the situation, not from the grammar alone.

The structure is:

• Sy = subject
• steek = finite verb
• die soom = object
• vas = separable particle

So the pattern is:

Subject + verb + object + particle

That gives:

Sy + steek + die soom + vas

This is a very useful pattern to recognize in Afrikaans, because many everyday verbs work like this.
