Sy trek haar blou rok aan, en ek trek my nuwe broek aan.

Here it means she.

Afrikaans sy can mean two different things depending on its job in the sentence:

• sy = she when it is a subject pronoun
• sy = his when it comes before a noun

In Sy trek haar blou rok aan, Sy is followed by the verb trek, so it is the subject: she.

Compare:

• Sy trek haar rok aan. = She puts on her dress.
• sy broek = his trousers

Haar here means her in the possessive sense: her blue dress.

Afrikaans haar can be:

• an object pronoun: I see her
• a possessive word: her dress

In this sentence it is possessive because it comes directly before the noun phrase blou rok.

So:

• haar rok = her dress
• ek sien haar = I see her

Because the full verb is aantrek, which is a separable verb.

In a main clause, Afrikaans often splits this kind of verb:

• the main verb part goes earlier: trek
• the particle goes to the end: aan

So:

• Sy trek haar blou rok aan.
• literally: She pulls her blue dress on
• natural English: She puts on her blue dress

The same happens in the second clause:

• ek trek my nuwe broek aan

It means to put on clothes, or to get dressed in something.

That is different from dra, which means to wear.

Compare:

• Sy trek haar rok aan. = She puts her dress on.
• Sy dra haar rok. = She is wearing her dress.

So aantrek focuses on the action of putting the clothes on.

Because each clause has its own verb.

The sentence has two coordinated clauses:

• Sy trek haar blou rok aan
• en ek trek my nuwe broek aan

Each clause needs its own complete verb form, so each one uses trek ... aan.

If you left out the first or second aan, that clause would feel incomplete.

This is about adjective forms before nouns.

In Afrikaans, adjectives often change form when they come before a noun:

• nuut → nuwe
• Die broek is nuut. = The trousers are new.
• my nuwe broek = my new trousers

But some adjectives, including blou, often stay the same:

• Die rok is blou. = The dress is blue.
• haar blou rok = her blue dress

So the learner-friendly way to remember it is:

• many adjectives add -e before a noun
• some do not, and blou is a common example

In Afrikaans, broek can refer to one pair of trousers/pants.

So:

• 'n broek = a pair of trousers / pants
• broeke = trousers / pants in the plural, usually meaning more than one pair

That is normal in Afrikaans, even though English often uses a plural word for one item.

Because the nouns already have possessive words:

• haar blou rok
• my nuwe broek

In Afrikaans, just like in English, you normally do not use an indefinite article together with a possessive.

So you say:

• my broek = my trousers
• haar rok = her dress

Not:

• my 'n broek
• haar 'n rok

The basic pattern is:

• subject
  • finite verb
    • rest of the sentence
      • separable particle

So here:

• Sy = subject
• trek = finite verb
• haar blou rok = object/noun phrase
• aan = separable particle

That gives:

• Sy trek haar blou rok aan.

The second clause follows the same pattern:

• ek trek my nuwe broek aan

Yes. On its own, trek often means pull, draw, or sometimes move/go depending on context.

But when you combine it with aan, it becomes aantrek, which often means put on or dress oneself.

Compare:

• trek = pull
• aantrek = put on

So the aan is not just extra—it changes the meaning of the verb.

This is a very common question, because separable verbs behave differently in different structures.

In a main clause, it is split:

• Sy trek haar blou rok aan.

In a subordinate clause, it is usually written together at the end:

• ... omdat sy haar blou rok aantrek.
• ... because she puts on her blue dress.

With te, it splits again:

• Sy wil haar blou rok aan te trek. is not standard
• correct: Sy wil haar blou rok aantrek. = She wants to put on her blue dress.
• with an infinitive using te in the right structure: om haar blou rok aan te trek = to put on her blue dress

So a good rule is:

• main clause: trek ... aan
• subordinate clause: aantrek
• infinitive with te: aan te trek
