Ukuran itu menunjukkan kelebaran meja.

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

So:

• ukuran itu = that measurement
• meja itu = that table

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

So the pattern is:

• noun + ini/itu

Examples:

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

In your sentence, itu is describing ukuran, not meja.

Ukuran comes from the root ukur, which means to measure.

The ending -an often turns a verb or root into a noun, so:

• ukur = measure
• ukuran = measurement, size, dimension

In this sentence, ukuran itu most naturally means something like:

• that measurement
• that size/dimension
• the measurement

The exact English wording depends on context. Malay often leaves this a bit flexible.

Menunjukkan means to show or to indicate.

It comes from the root tunjuk, which is related to showing or pointing.

The full form is:

• tunjuk = show/point
• menunjukkan = show, indicate

This word includes:

• meN- prefix, which often forms an active verb
• -kan suffix, which often makes the verb transitive or gives it a sense like show something, cause something to be shown, or indicate

So in this sentence, menunjukkan is a normal active verb meaning indicates/shows.

Kelebaran is a noun formed from lebar, which means wide or width-related.

Structure:

• lebar = wide / width
• ke-...-an → often forms an abstract noun
• kelebaran = width, broadness

So kelebaran meja means the width of the table.

A useful thing to know is that Malay often allows both a simpler form and a more noun-like derived form:

• lebar meja = the table’s width
• kelebaran meja = the width of the table

The version with kelebaran sounds a bit more formal, technical, or abstract.

Malay usually does not use a separate word like English of in this kind of structure.

Instead, Malay often puts nouns directly together:

• kelebaran meja = width of the table
• warna kereta = color of the car
• pintu rumah = door of the house / house door

So the pattern is often:

• noun + noun

The relationship is understood from context.

In kelebaran meja, the second noun meja tells you what the width belongs to.

It refers to ukuran.

So the sentence means:

• that measurement indicates the width of the table

If you wanted that table, you would place itu after meja:

• kelebaran meja itu = the width of that table

Compare:

• Ukuran itu menunjukkan kelebaran meja.
  = That measurement indicates the width of the table.

• Ukuran itu menunjukkan kelebaran meja itu.
  = That measurement indicates the width of that table.

Position matters a lot here.

Yes, very often you can.

Both can refer to the width of the table, but there is a slight difference in feel:

• lebar meja = simpler, more everyday
• kelebaran meja = more abstract, formal, or technical

For example:

• Lebar meja ini 80 sentimeter.
  = The width of this table is 80 centimeters.

That sounds very natural.

So your sentence is understandable, but many speakers might more naturally say:

• Ukuran itu menunjukkan lebar meja.

Still, kelebaran meja is grammatically fine.

Yes, it is grammatical and understandable, but it sounds a little formal or technical.

A more everyday version might be:

• Ukuran itu menunjukkan lebar meja.

Why? Because in practical descriptions of dimensions, Malay often uses the simpler measurement word directly:

• panjang = length
• lebar = width
• tinggi = height

So for dimensions, speakers often prefer:

• panjang meja
• lebar meja
• tinggi meja

The form kelebaran is not wrong; it just feels a bit more like an abstract noun.

Malay does not have articles that work like English a and the.

Whether something is a table, the table, or just table is usually understood from context.

In your sentence:

• ukuran itu is specific because of itu
• meja is understood from context as the table or a table, depending on the situation

So Malay often leaves this unstated unless it needs to be made clear.

That is why one Malay sentence can sometimes match several English translations.

Malay verbs do not usually change form for tense the way English verbs do.

So menunjukkan by itself does not specifically mean present tense. It can mean:

• shows
• is showing
• showed
• will show

The time is normally understood from context or shown with time words such as:

• semalam = yesterday
• sekarang = now
• esok = tomorrow

So Ukuran itu menunjukkan kelebaran meja can naturally be interpreted as That measurement shows/indicates the width of the table, because that is the most neutral reading in English.

Yes. Ukuran is a flexible word.

Depending on context, it can mean:

• measurement
• size
• dimension
• standard/measure

In this sentence, because it is followed by menunjukkan kelebaran meja, the meaning is something like measurement or dimension reading.

That flexibility is normal in Malay. Often the surrounding words tell you which English word fits best.
