Ubat kumur itu berada di sini.

In Malay, demonstratives like ini and itu normally come after the noun, not before it.

So the pattern is:

• ubat kumur ini = this mouthwash
• ubat kumur itu = that mouthwash

To an English speaker, this can feel backwards at first, but it is the normal Malay word order.

Ubat kumur is a two-word noun phrase that functions as a single idea: mouthwash.

• ubat = medicine / remedy
• kumur = to gargle / rinse the mouth

So ubat kumur literally suggests something like gargling medicine, but in normal usage it means mouthwash. Malay often builds vocabulary this way, by combining familiar words into a compound expression.

Berada means to be located, to be situated, or simply to be in a place.

In this sentence, it shows location clearly: the mouthwash is in this place. It is a slightly more formal or explicit way to talk about where something is.

So berada di sini means is located here.

Yes. In everyday Malay, Ubat kumur itu di sini is natural and common.

Malay often allows location sentences without a word that directly matches English is. So both of these work:

• Ubat kumur itu berada di sini.
• Ubat kumur itu di sini.

The version with berada sounds a bit more explicit or slightly more formal.

They are related, but they are not always used in exactly the same way.

• ada can mean there is/are, to exist, to have, or to be present
• berada is more specifically to be located or to be in a place

For location, both can appear:

• Ubat kumur itu ada di sini.
• Ubat kumur itu berada di sini.

But berada is not used for possession the way ada can be. For example:

• Saya ada wang. = I have money.
• Saya berada wang. = incorrect

So in this sentence, berada is a location verb.

Because di here is a preposition meaning in / at / on, and prepositions are written separately from the following word.

So:

• di sini = here
• di rumah = at home
• di sekolah = at school

This is different from di- as a verb prefix, which is written together with the verb:

• dibuka = opened
• ditulis = written

That spelling difference is very important in Malay.

Often, no separate word is needed.

Malay frequently makes sentences without a direct equivalent of is/am/are, especially in simple statements about identity, description, or location.

For example:

• Dia guru. = He/She is a teacher.
• Rumah itu besar. = That house is big.
• Ubat kumur itu di sini. = The mouthwash is here.

So if you are looking for a Malay word that always equals English is, you usually will not find one.

Grammatically, itu is a demonstrative, so its basic meaning is that.

However, in real usage, noun + itu can sometimes sound closer to English the + noun, especially when the thing is already known from context. So ubat kumur itu may be understood as either:

• that mouthwash
• the mouthwash

Which one sounds best in English depends on the situation, but the Malay structure stays the same.

Yes. If the mouthwash is near the speaker or you want to say this mouthwash, you would use ini:

• Ubat kumur ini berada di sini.

That may sound a little repetitive in English because both ini and di sini point to nearness, but it is grammatically fine in Malay. The choice between ini and itu depends on context, distance, and what the speaker is pointing out.

The structure is:

Subject + location verb + place

So in this sentence:

• Ubat kumur itu = subject
• berada = location verb
• di sini = place expression

A useful pattern to remember is:

[noun phrase] + berada + di + [place]

For example:

• Buku itu berada di meja.
• Kunci saya berada di dalam beg.

This makes the sentence easy to reuse with other nouns and locations.
