Kasa itu di bawah plaster.

In Malay, demonstratives like ini and itu usually come after the noun.

So:

• kasa itu = that gauze / the gauze
• plaster itu = that plaster / the plaster

This is different from English, where we put that before the noun.

So Malay does:

• rumah itu = that house
• buku ini = this book

not itu kasa in normal usage.

Malay often leaves out the verb to be when describing location, identity, or qualities in simple sentences.

So English:

• The gauze is under the plaster

becomes Malay:

• Kasa itu di bawah plaster

There is no need for a separate word meaning is here.

This is very common in Malay:

• Ali di rumah = Ali is at home
• Buku itu merah = The book is red
• Dia guru = He/She is a teacher

Yes. di bawah is a location phrase meaning under or below.

It is made of:

• di = at/in/on, a preposition used for location
• bawah = lower part, underneath

Together:

• di bawah = under / below

Other similar examples:

• di atas = on / above
• di dalam = in / inside
• di luar = outside

So in this sentence, di bawah plaster means under the plaster.

Because here di is a preposition showing location, and prepositional di is written separately from the following word.

So:

• di bawah = under
• di rumah = at home
• di meja = on the table

This is different from di- used as a passive prefix, which is written together:

• dibuka = opened
• ditulis = written
• dibalut = wrapped/bandaged

A useful rule:

• di + place/location → usually separate
• di- + verb → usually attached

Literally, itu means that. But in real Malay, itu is also often used to make a noun feel more specific or definite, so it can sound like English the as well.

So kasa itu could be understood as:

• that gauze
• the gauze

The exact nuance depends on context.

This is why learners often see itu translated in more than one way.

Yes, you often can.

• Kasa itu di bawah plaster sounds like the/that gauze is under the plaster
• Kasa di bawah plaster can sound more general or less specifically identified

Malay often omits words that English would use to mark definiteness. Whether itu is included depends on how specific the speaker wants to be.

So both can be possible, but itu makes kasa feel more definite.

It is a commonly used borrowed word. Malay contains many loanwords, including from English.

plaster is often used in medical or everyday contexts, especially for things like:

• adhesive plaster
• a plaster bandage
• a cast, depending on context

Malay also has other related words depending on the exact meaning, such as balutan or more specific medical terms, but plaster is very normal in everyday usage.

So this sentence sounds natural if the context is medical dressing or bandaging.

The basic structure is:

• Kasa itu = subject noun phrase
• di bawah plaster = predicate showing location

So the pattern is:

[noun phrase] + [location phrase]

This is a very common Malay sentence type.

Examples:

• Buku itu di atas meja = The book is on the table
• Kucing itu di luar rumah = The cat is outside the house
• Telefon saya di dalam beg = My phone is in the bag

The normal, neutral order is:

• Kasa itu di bawah plaster

You can sometimes change word order for emphasis, but for a learner, it is best to stick with:

subject + location

If you reverse things too freely, the sentence may sound unnatural or may need a different structure.

So the safest pattern is:

• X di bawah Y
• X di atas Y
• X di dalam Y

A simple pronunciation guide:

• kasa → roughly KAH-sah
• itu → roughly EE-too
• di → roughly dee
• bawah → roughly BAH-wah
• plaster → often pronounced close to English PLAS-ter, though adapted to Malay speech rhythm

A few useful notes:

• Malay pronunciation is generally quite regular.
• The a in kasa and bawah is usually like the a in father, not like the English cat vowel.
• Stress in Malay is usually not as strong or dramatic as in English.

Yes, kasa is a normal word, especially in medical or first-aid contexts. It refers to gauze, the light woven material used in dressings and bandages.

So in this sentence, kasa is the piece of gauze, and the sentence tells you where it is located relative to the plaster.

This kind of vocabulary is especially common in clinics, hospitals, first aid, and instructions about wound care.
