Zij draagt een paarse jas.

In this sentence, Zij means she.

Dutch zij can mean:

• she (singular)
• they (plural)

You can usually tell which one is meant from the verb form:

• Zij draagt = She wears/is carrying
• Zij dragen = They wear/are carrying

So here, because the verb is draagt (singular), zij must mean she.

Also, in everyday Dutch, zij is often shortened to ze in normal speech:

• Ze draagt een paarse jas.

Draagt is the third-person singular form of the verb dragen.

dragen can mean:

• to wear
• to carry
• sometimes to bear

In this sentence, with clothing, it means to wear:

• Zij draagt een paarse jas. = She is wearing a purple coat/jacket.

A few present-tense forms of dragen:

• ik draag = I wear
• jij draagt = you wear
• hij/zij draagt = he/she wears
• wij dragen = we wear
• zij dragen = they wear

This is because Dutch adjectives usually take an -e ending when they come before a noun.

The basic adjective is:

• paars = purple

But before jas, it becomes:

• een paarse jas

So:

• een paarse jas = a purple coat

This -e is very common in Dutch:

• een rode auto = a red car
• een grote hond = a big dog
• de mooie tafel = the beautiful table

A useful beginner rule:

• If the adjective is before the noun, it is often given -e.

Jas is simply the normal Dutch word for coat or jacket.

• jas = coat/jacket

Jasje is a diminutive form, meaning something like:

• little jacket
• small jacket
• sometimes just a lighter or cuter-sounding jacket

So:

• een jas = a coat/jacket
• een jasje = a little jacket / jacket

In your sentence, jas is the normal word and fits perfectly.

Een is the indefinite article, meaning a or an.

So:

• een jas = a coat/jacket

Do not confuse this with the number één, which means one.

Usually:

• een = a/an
• één = one (with emphasis)

Examples:

• Ik heb een jas. = I have a coat.
• Ik heb één jas. = I have one coat.

In normal writing, the article is usually written without accents: een.

The word order is very straightforward:

• Zij = subject
• draagt = verb
• een paarse jas = object / what she is wearing

So the structure is:

Subject + Verb + Object

This is the normal Dutch main-clause order, just like in English:

• She wears a purple coat.
• Zij draagt een paarse jas.

A rough English-friendly guide is:

• Zij ≈ like zeye
• draagt ≈ something like drahkht / drakht
• een ≈ usually a soft uhn or un
• paarse ≈ PAHR-suh
• jas ≈ yahs

A few important pronunciation notes:

• ij in zij is a Dutch vowel sound, often approximated as eye
• g in Dutch can be a throaty sound, but in draagt the ending is more about the cht cluster
• j in Dutch sounds like English y, so jas sounds like yas

Yes, but mostly in style and emphasis, not basic meaning.

• zij = fuller form
• ze = unstressed, very common everyday form

So both can mean she:

• Zij draagt een paarse jas.
• Ze draagt een paarse jas.

The second one is especially common in spoken Dutch.

Learners will often see zij in textbooks because it is clearer, but in real conversation ze is extremely frequent.

It can mean coat or jacket, depending on context.

Dutch jas is broader than either single English word. So translation depends on the situation:

• winter clothing: often coat
• lighter outerwear: often jacket

That is why you may see different English translations for the same Dutch sentence.

No. Dragen has a wider meaning than just clothing.

It can be used for:

• wearing clothes or accessories
  
  • Zij draagt een hoed. = She is wearing a hat.
• carrying something
  
  • Hij draagt een doos. = He is carrying a box.
• more abstract meanings such as bearing or supporting, depending on context

So in this sentence, context tells you it means wearing, because the object is een paarse jas.

Yes, this is a completely natural Dutch sentence.

It is simple, grammatical, and everyday:

• Zij draagt een paarse jas.

In casual speech, many people would more often say:

• Ze draagt een paarse jas.

But your sentence is perfectly correct and natural.
