Kami menukar barang yang salah itu.

Kami means we, but it is the exclusive form: it includes the speaker and someone else, but not the listener.

So Kami menukar barang yang salah itu suggests:

• we exchanged/replaced the wrong item
• but you are not included in that we

If the listener were included, Malay would usually use kita instead.

Menukar comes from the root tukar, which is about changing, exchanging, or replacing something.

In this sentence, depending on context, it could mean:

• exchanged
• replaced
• swapped

For example, in a shop situation, menukar barang often means to exchange/replace an item.

The prefix meN- (here appearing as men-) often makes a verb active and more natural in full sentences.

So:

• tukar = change/exchange/swap (root form)
• menukar = to exchange/replace; actively doing the action

In everyday speech, Malaysians may sometimes use the root form casually, but menukar is the more grammatically complete form in standard Malay.

Barang means item, thing, or goods.

In this sentence, it usually means the item or the goods being exchanged. Malay nouns do not automatically show singular or plural the way English nouns do.

So barang can mean:

• item
• items
• goods

You understand the number from context. In this sentence, English may translate it as the item if only one item is meant.

Yang introduces a phrase that describes the noun before it.

Here:

• barang = item
• yang salah = that is wrong / incorrect / mistaken

So barang yang salah means:

• the wrong item
• literally, the item that is wrong

A useful way to think of yang is that it often works like:

• that
• which
• sometimes just a marker linking a noun to its description

In Malay, descriptive words often come after the noun, not before it as in English.

So:

• English: the wrong item
• Malay: barang yang salah = item that is wrong

This noun-first pattern is very common in Malay.

Itu means that, and in Malay demonstratives usually come after the noun phrase.

So:

• English: that wrong item
• Malay: barang yang salah itu

The order is:

• noun: barang
• descriptive phrase: yang salah
• demonstrative: itu

This is completely normal Malay word order.

It can feel like either in English, depending on context.

Literally, it is closer to:

• that item which was wrong or
• that wrong item

Natural English usually shortens this to:

• that wrong item
• the wrong item
• the incorrect item

Malay often uses structures that are slightly more explicit than the most natural English phrasing.

No, not by itself. Malay verbs usually do not change form for tense.

So menukar could mean:

• exchange
• exchanged
• are exchanging
• will exchange

You know the time from context or from time words such as:

• semalam = yesterday
• sekarang = now
• esok = tomorrow
• sudah = already
• akan = will

Without extra context, Kami menukar barang yang salah itu could be understood as past or present depending on the situation.

Yes. Salah can mean:

• wrong
• incorrect
• mistaken
• sometimes at fault, depending on context

In barang yang salah, it most naturally means:

• the wrong item
• the incorrect item
• possibly the mistaken item in a delivery/order situation

So if someone received the wrong package, this phrase fits very well.

The structure is:

• Kami = subject
• menukar = verb
• barang yang salah itu = object noun phrase

So the pattern is:

Subject + Verb + Object

More literally:

• Kami = we
• menukar = exchanged/replaced
• barang yang salah itu = that wrong item

This is a very common Malay sentence pattern.

Yes, in a very literal sense it could, because menukar and barang are both fairly broad words.

But in normal usage, the most likely meaning depends on context:

• in a shop or customer-service context: We exchanged/replaced the wrong item
• in a general context: We changed/swapped that wrong item

So the sentence itself allows some flexibility, but real-life context usually makes the intended meaning clear.

A common passive version would be:

Barang yang salah itu ditukar oleh kami.

This means roughly:

• That wrong item was exchanged by us.

Compare:

• Kami menukar barang yang salah itu.
  We exchanged the wrong item.
  Active; focus on we

• Barang yang salah itu ditukar oleh kami.
  The wrong item was exchanged by us.
  Passive; focus on the item

Malay uses active and passive quite often, and both are very important to learn.
