Kedalaman kabinet itu sesuai.

Because dalam is the root word meaning deep or inside, while kedalaman is the noun depth.

Malay often uses the pattern ke-...-an to form abstract nouns. So:

• dalam = deep
• kedalaman = depth

So in this sentence, kedalaman is the thing being talked about: the cabinet’s depth.

Yes. Kedalaman kabinet means the depth of the cabinet or cabinet depth.

Malay commonly shows this kind of relationship by putting the main noun first and the related noun after it:

• kedalaman kabinet = depth of the cabinet
• literally: depth cabinet

This is different from English, where we often put the describing noun first, as in cabinet depth.

Itu usually means that, and it comes after the noun in Malay:

• kabinet itu = that cabinet

But in real usage, itu can also make the noun phrase feel more definite, a bit like the in English. So depending on context, kabinet itu might be understood as:

• that cabinet
• the cabinet

Malay does not have a direct word exactly equal to English the, so words like itu often help give that definite feeling.

Because Malay often leaves out the verb to be in simple sentences like this.

So:

• Kedalaman kabinet itu sesuai
• literally: The depth of that cabinet suitable

In natural Malay, that already means The depth of the cabinet is suitable. You do not need an extra word for is in normal speech.

Yes, you might see that, especially in more formal writing, but in everyday Malay it is usually more natural to leave it out.

So:

• Kedalaman kabinet itu sesuai = natural, common
• Kedalaman kabinet itu adalah sesuai = more formal or stiff

In practice, learners should be comfortable with the version without adalah, because that is very common.

Because sesuai is the predicate here—the part that says something about the subject.

The sentence structure is:

• Kedalaman kabinet itu = subject
• sesuai = predicate adjective

So the whole sentence is basically:

• The cabinet’s depth
  • is suitable

Malay often puts the adjective after the subject when the adjective is the main statement about that subject.

Sesuai means suitable, appropriate, fitting, or right for the situation.

It is a very common word and can be used in many contexts:

• saiz itu sesuai = that size is suitable
• warna ini sesuai = this color is suitable
• masa itu sesuai = that time is suitable

So in your sentence, it means the cabinet’s depth is acceptable or appropriate for the purpose being discussed.

Not always. It can stand alone if the context is already clear.

But very often, Malay adds more information:

• sesuai untuk dapur kecil = suitable for a small kitchen
• sesuai dengan reka bentuk ini = suitable for / matches this design

So your sentence is complete as it is, but it could also be expanded, for example:

• Kedalaman kabinet itu sesuai untuk ruang ini.
• The depth of the cabinet is suitable for this space.

You can, but it changes the feel.

• Kedalaman kabinet itu sesuai = the depth of that/the specific cabinet is suitable
• Kedalaman kabinet sesuai = more general, less specific, and often sounds less complete unless the context is very clear

So itu helps point to a particular cabinet and makes the sentence sound more grounded.

Kabinet is a loanword, but it is a normal and widely used Malay word.

Depending on the object and the region, you may also hear words like:

• almari
• lemari

But kabinet is very common, especially for a cabinet unit in furniture or interior contexts. So there is nothing unusual about it here.
