Ek trek my jas aan omdat die wind koud is.

Because aantrek is a separable verb in Afrikaans.

• The full verb is aantrek = to put on / to get dressed
• In a main clause, the conjugated part goes into the normal verb position, and the particle aan moves to the end.

So:

• Ek trek my jas aan = I put on my coat

But in forms where the verb stays together, you can get:

• Ek wil my jas aantrek = I want to put on my coat

This is very similar to separable verbs in Dutch and somewhat like English phrasal verbs such as put on.

Afrikaans usually follows the verb-second pattern in main clauses.

That means the finite verb comes early in the sentence, typically in the second position:

• Ek = subject
• trek = finite verb
• my jas = object
• aan = separated particle

So the structure is:

Ek | trek | my jas | aan

This is normal Afrikaans main-clause order.

Because omdat introduces a subordinate clause, and in Afrikaans the finite verb usually moves to the end of that clause.

So:

• Main clause: Die wind is koud
• After omdat: omdat die wind koud is

This is one of the most important word-order patterns to learn in Afrikaans.

Omdat means because.

Afrikaans also has want, which can also mean because, but the grammar is different:

• Ek trek my jas aan omdat die wind koud is.
• Ek trek my jas aan, want die wind is koud.

The difference:

• omdat creates a subordinate clause, so the verb goes to the end: koud is
• want does not do that, so normal word order stays: is koud

Both are common, but omdat is especially useful when you want a more tightly connected because-clause.

Yes. Here die is the definite article, meaning the.

So:

• die wind = the wind
• die jas = the coat

A useful thing for English speakers: Afrikaans does not have grammatical gender articles like German or some older Dutch patterns. You do not have to learn separate words for the based on masculine, feminine, or neuter nouns.

So die is used very widely for the.

Because my is the normal possessive adjective meaning my when it comes before a noun.

So:

• my jas = my coat
• my boek = my book

Afrikaans keeps this simple. You do not need extra agreement endings here.

Also note:

• my before a noun = my
• myne is more like mine, and it is not normally used directly before a noun

So my jas is the correct form.

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

In Afrikaans:

• After is: Die wind is koud = The wind is cold
• Before a noun: die koue wind = the cold wind

So:

• koud = used as the description after the verb
• koue = often used before a noun

That is why the sentence has die wind koud is, not die wind koue is.

Usually it means put on my coat.

• Ek trek my jas aan = I put on my coat

If you want to say that you are already wearing it, Afrikaans often uses:

• Ek dra my jas = I am wearing my coat

So aantrek focuses more on the action of putting clothes on, while dra often describes the state of wearing them.

Yes, absolutely.

You can say:

Omdat die wind koud is, trek ek my jas aan.

This means the same thing: Because the wind is cold, I put on my coat.

Notice the word order in the main clause after the subordinate clause:

• Omdat die wind koud is, trek ek my jas aan.

After the omdat-clause comes first, the finite verb trek comes before the subject ek in the main clause. This is normal Afrikaans word order.

Yes. Is is the verb to be, and it is required here.

• die wind koud is = the wind is cold

Even though koud already gives the description, Afrikaans still needs the linking verb is, just like English needs is in the wind is cold.

So you cannot leave it out in standard Afrikaans.
