Ek is laat.

• Ek = I
• is = am / is / are
• laat = late

So the sentence is built very directly: I am late.

Afrikaans uses is as the present-tense form of to be in sentences like this.

A very important difference from English is that Afrikaans does not change the verb to be in the present tense the way English does:

• Ek is = I am
• Jy is = you are
• Hy is = he is
• Ons is = we are

So in this sentence, is is simply the correct present-tense verb after Ek.

Because this is a normal Afrikaans sentence pattern:

subject + verb + complement

So:

• Ek = subject
• is = verb
• laat = complement describing the subject

This is very similar to English I am late.

Yes. In Ek is laat, laat is functioning like an adjective after the verb is. It describes Ek.

This is similar to English sentences like:

• I am tired
• She is happy
• We are ready

So laat is describing a state: being late.

A rough English-friendly guide would be:

• Ek ≈ eck
• is ≈ iss
• laat ≈ laaht

A few pronunciation notes:

• Ek has a short vowel.
• laat has a longer aa sound than English late.
• The t at the end of laat is clearly pronounced.

A rough full pronunciation might be: eck iss laaht.

No. Ek is laat specifically means I am late because Ek means I.

If you want It is late, you would say:

• Dit is laat

So the subject word matters a lot:

• Ek = I
• Dit = it

You use the Afrikaans double negative:

Ek is nie laat nie.

This means I am not late.

Notice the two nie words:

• one after the verb
• one at the end of the sentence

That double negative pattern is a very common feature of standard Afrikaans.

In a simple yes/no question, Afrikaans usually puts the verb first:

Is ek laat?

This means Am I late?

So compare:

• Ek is laat. = I am late.
• Is ek laat? = Am I late?

Yes, it is completely natural and correct.

It is the normal straightforward way to say I am late.

Depending on context, speakers might also say longer versions such as:

• Ek is bietjie laat. = I am a little late.
• Ek is te laat. = I am too late.

But Ek is laat by itself is perfectly normal.

• laat = late
• te laat = too late

So:

• Ek is laat. = I am late.
• Ek is te laat. = I am too late.

The word te here means too in the sense of more than is acceptable or useful.

Yes. Laat can have other meanings in other contexts, which can be confusing for learners.

For example, it can be related to ideas like:

• late
• let / allow
• make someone do something in certain structures

But in Ek is laat, the meaning is clearly late.

So for this sentence, you can safely understand laat as an adjective meaning late.
