Blus putih itu lebih longgar daripada kemeja kerjanya, jadi dia memakainya ke kantor hari ini.

In Indonesian, descriptive adjectives usually come after the noun.

• blus putih = white blouse
• rumah besar = big house
• mobil baru = new car

So blus putih follows the normal Indonesian noun + adjective order.

Itu here means something like that or the one we’re talking about. In Indonesian, demonstratives like ini and itu usually come after the noun phrase.

• blus putih itu = that white blouse
• rumah besar itu = that big house

In context, itu often helps make the noun more definite, similar to the in English, even though Indonesian does not have a direct word for the.

This is the standard Indonesian pattern for comparisons:

• lebih = more
• adjective = longgar = loose / roomier
• daripada = than

So:

• lebih longgar daripada kemeja kerjanya
  = looser than his/her work shirt

This same pattern works with many adjectives:

• lebih besar daripada = bigger than
• lebih murah daripada = cheaper than
• lebih cepat daripada = faster than

Longgar usually means loose, not tight, or roomy. For clothing, it suggests that something fits less tightly on the body.

So here, lebih longgar means the blouse has a looser fit than the work shirt.

Depending on context, longgar can also mean things like relaxed or not strict, but in this sentence it clearly refers to clothing fit.

The suffix -nya often marks possession, similar to his, her, or sometimes their in English.

So:

• kemeja kerjanya = his/her work shirt

This is very natural Indonesian.
A form like kemeja kerja dia is also possible in conversation, but kemeja kerjanya is smoother and more compact.

Also notice the structure:

• kemeja kerja = work shirt
• kemeja kerjanya = his/her work shirt

So kerja is describing the kind of shirt, and -nya shows whose it is.

Not quite. -nya can do several different jobs in Indonesian, and here it behaves differently in the two words.

1. kemeja kerjanya
   Here -nya marks possession:

   • his/her work shirt

2. memakainya
   Here -nya is the object:

   • wear it

So in this sentence:

• kerjanya = his/her work
• kemeja kerjanya = his/her work shirt
• memakainya = to wear it

This is a very common feature of Indonesian: the same ending -nya can mean different things depending on context.

Because the speaker wants to say wear it, not just wear in general.

• memakai = to wear / to use
• memakainya = to wear it / use it

The -nya refers back to blus putih itu.

So the meaning is:

• jadi dia memakainya = so he/she wore it

If you said only dia memakai, it would sound incomplete unless the object were stated elsewhere.

It could sometimes be understood from context, but Indonesian often repeats the subject for clarity, especially in full written sentences.

• Blus putih itu lebih longgar daripada kemeja kerjanya, jadi dia memakainya...

This is natural and clear: the blouse is looser, so he/she wore it.

If the subject were omitted, the sentence might sound less complete or less explicit in standard writing. Indonesian does allow subject omission in some contexts, but repeating dia here is normal.

No. In this sentence, jadi means so, therefore, or as a result.

Indonesian jadi can have different meanings depending on context:

• jadi = become
• jadi = so / therefore
• jadi = finished / done in some situations

Here it connects cause and result:

• The blouse is looser than the work shirt, so he/she wore it to the office today.

Ke is the preposition used for movement toward a place.

• ke kantor = to the office
• ke sekolah = to school
• ke rumah = to home / to the house

So:

• memakainya ke kantor = wore it to the office

If you were talking about location instead of movement, you would often use di:

• di kantor = at the office

Hari ini means today. In this sentence it comes at the end, which is very natural:

• ... ke kantor hari ini = ... to the office today

Indonesian word order is fairly flexible, so you could also say:

• Hari ini, dia memakainya ke kantor.
• Dia memakainya ke kantor hari ini.

All are understandable, but the original sentence sounds natural and straightforward.

Yes, they refer to different kinds of clothing.

• blus = blouse, usually a woman’s top
• kemeja = shirt, especially a buttoned shirt

So the sentence contrasts a blouse with a work shirt. That is why the comparison is about fit: the blouse is looser than the shirt normally worn for work.

In everyday speech, some speakers do use dari in comparisons, but daripada is the clearer and more standard form after comparatives like lebih.

So the best version is:

• lebih longgar daripada kemeja kerjanya

This is the safest choice for learners and the most standard in careful Indonesian.
