Anak laki-laki itu melempar bola ke lapangan.

In Indonesian, words like ini and itu usually come after the noun they describe.

So:

• anak laki-laki itu = that boy / the boy
• bola itu = that ball / the ball

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

So the pattern is:

• noun + itu
• noun + ini

Examples:

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

In this sentence, anak laki-laki itu most naturally means that boy or sometimes the boy, depending on context.

Anak laki-laki means boy.

Literally:

• anak = child
• laki-laki = male, man, masculine

Together, anak laki-laki means male child, which is just boy in natural English.

A related expression is:

• anak perempuan = girl

So:

• anak laki-laki itu = that boy
• anak perempuan itu = that girl

No, it is not plural here.

Laki-laki is just the normal word for male/man. The repetition is part of the word itself. Indonesian often has repeated forms, but they do not always mean plurality.

So in this case:

• laki-laki = male / man
• anak laki-laki = boy

It does not mean boys.

Plural in Indonesian is often shown by context, numbers, or sometimes reduplication of the whole noun, for example:

• anak-anak = children

But laki-laki is simply the standard word, not a plural form.

Yes. The root is lempar, which means throw.

The form melempar is built from the root lempar with the active verb prefix meN-. In this case, it becomes melempar.

So:

• lempar = throw / to throw
• melempar = to throw, throws, is throwing

This prefix often marks an active verb, where the subject is doing the action.

Here:

• Anak laki-laki itu melempar bola = The boy throws/is throwing/threw the ball

The exact time is not shown by the verb form itself.

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

So melempar can mean:

• throws
• is throwing
• threw

The time is usually understood from:

1. context
2. time words

For example:

• kemarin = yesterday
• sekarang = now
• besok = tomorrow
• sedang = in the middle of doing something

Examples:

• Anak laki-laki itu melempar bola. = The boy throws / is throwing / threw the ball.
• Anak laki-laki itu sedang melempar bola. = The boy is throwing the ball.
• Kemarin anak laki-laki itu melempar bola. = Yesterday the boy threw the ball.

So in your sentence, the tense depends on context.

Indonesian generally does not use articles like a, an, and the.

So:

• bola can mean a ball, the ball, or just ball
• lapangan can mean a field, the field, or field

The listener understands which one is meant from context.

If you want to make something more specific, Indonesian often uses:

• itu = that / the
• ini = this

Examples:

• bola = a ball / the ball
• bola itu = that ball / the ball
• lapangan itu = that field / the field

So the sentence leaves bola and lapangan context-based.

Ke means to and shows movement toward a place.

So:

• ke lapangan = to the field / onto the field

This is used because the ball is being thrown toward the field.

Compare:

• ke = to, toward
• di = in, at, on

Examples:

• Dia pergi ke sekolah. = He goes to school.
• Dia ada di sekolah. = He is at school.

So:

• melempar bola ke lapangan = throw the ball to/toward the field
• bola di lapangan = the ball is in/on the field

Not if you want to keep the same meaning.

• ke lapangan shows direction or destination
• di lapangan shows location

So:

• Anak laki-laki itu melempar bola ke lapangan. = The boy threw/throws the ball to the field.
• Anak laki-laki itu melempar bola di lapangan. = The boy threw/throws the ball at/on the field.

The second sentence changes the meaning. It tells you where the throwing happens, not where the ball goes.

Not always.

Lapangan can mean different kinds of open or flat areas, depending on context, such as:

• field
• court
• मैदान/open ground
• yard
• square/open space

For example:

• lapangan sepak bola = football/soccer field
• lapangan basket = basketball court

So in your sentence, lapangan could be field in a general sense, but the exact translation depends on the situation.

Yes. This is a very normal Indonesian sentence pattern:

• Subject + Verb + Object + Place/Direction

Breaking it down:

• Anak laki-laki itu = subject
• melempar = verb
• bola = object
• ke lapangan = direction/place phrase

So the structure is:

Anak laki-laki itu melempar bola ke lapangan.

This is very similar to standard English word order:

The boy throws the ball to the field.

Yes, but the basic version you have is the most straightforward.

For example, Indonesian can move phrases around for emphasis:

• Anak laki-laki itu melempar bola ke lapangan.
• Ke lapangan, anak laki-laki itu melempar bola.

The second one is possible, but it sounds more marked or emphatic, like emphasizing where the ball went.

You could also make a passive sentence:

• Bola dilempar anak laki-laki itu ke lapangan. = The ball is thrown/was thrown by the boy to the field.

So yes, rearrangement is possible, but your original sentence is the most neutral and natural for learners.

Because Indonesian often leaves that out unless it is needed.

Seorang means a/one person and is used with humans:

• seorang anak laki-laki = a boy
• seorang guru = a teacher

But in your sentence, the noun phrase already has itu, which makes it specific:

• anak laki-laki itu = that boy / the boy

So seorang would not fit naturally there.

Compare:

• Seorang anak laki-laki melempar bola. = A boy throws/threw a ball.
• Anak laki-laki itu melempar bola. = That boy / the boy throws/threw a ball.

Yes, melempar is correct and natural, especially in standard Indonesian.

In casual speech, some speakers may shorten or simplify certain verb forms depending on region and situation, but melempar is absolutely normal and useful to learn.

For a beginner, it is best to treat this as the standard form:

• melempar = to throw

So the sentence is good Indonesian and not overly formal.
