Dari balkoni pangsapuri itu, kakak saya melihat seorang lelaki berjalan cepat ke hujung lorong.

This is a fronted prepositional phrase meaning From the balcony of that apartment.

Malay often puts location or viewpoint information at the beginning of a sentence to set the scene. So:

• Dari = from
• balkoni = balcony
• pangsapuri itu = that apartment

The core sentence is still:

• kakak saya melihat seorang lelaki berjalan cepat ke hujung lorong
• my older sister saw a man walking quickly to the end of the lane

Putting Dari balkoni pangsapuri itu first gives a more natural narrative feel: first the setting, then the action.

In the most natural reading, itu points to pangsapuri: that apartment.

So:

• balkoni pangsapuri itu = the balcony of that apartment

Malay often places itu after the whole noun phrase, and it can feel a little broader than English word-for-word structure. In practice, learners should understand this phrase as referring to a specific apartment whose balcony is being mentioned.

In Malay, possession usually works as:

• noun + possessor

So:

• kakak saya = my older sister
• buku saya = my book
• rumah mereka = their house

English puts the possessor first; Malay usually puts it after the noun.

Usually, yes: kakak means older sister.

But it can also be used:

• as a form of address for an older female
• more generally in social situations to refer politely to an older young woman

In this sentence, though, kakak saya clearly means my older sister.

Seorang is the classifier used for one person.

So:

• seorang lelaki = a man
• literally: one-person man

Malay often uses classifiers when counting or introducing singular nouns, especially people and objects. For people:

• seorang guru = a teacher
• seorang wanita = a woman

In casual speech, classifiers are sometimes dropped, but in standard, careful Malay, seorang lelaki is very natural.

It can do both, depending on context.

• lelaki can mean man
• it can also mean male

In seorang lelaki, it clearly means a man, because it refers to one adult male person.

Malay verbs do not usually change form for tense.

So melihat can mean:

• see
• saw
• is seeing
• was seeing

The time is usually understood from context, or shown with time words if needed, such as:

• semalam = yesterday
• tadi = earlier
• sekarang = now

In your sentence, the English meaning may be past, but the Malay verb melihat itself does not change.

Melihat is the main verb of the sentence, meaning to see.

Structure:

• kakak saya = subject
• melihat = main verb
• seorang lelaki = object
• berjalan cepat ke hujung lorong = phrase describing what the man was doing

So the sister is the one doing the seeing.

It actually is very close in structure:

• berjalan = walk / walking
• cepat = fast / quickly

Malay often uses adjectives in places where English would prefer an adverb. So:

• berjalan cepat literally looks like walk fast
• natural English becomes walk quickly or walk fast

This is very common in Malay:

• bercakap perlahan = speak slowly
• lari laju = run fast

The prefix ber- often forms an intransitive verb, especially one describing an action done by the subject.

Here:

• jalan = road, path, or the root related to movement/walking
• berjalan = to walk / to be walking

You do not need to translate ber- separately every time, but it is useful to recognize that it often marks a verb of action or state involving the subject.

It describes the man.

So the sentence means:

• My older sister saw a man who was walking quickly to the end of the lane

Malay often places this kind of verb phrase directly after the noun it describes. Here, seorang lelaki berjalan cepat ke hujung lorong is understood as a man walking quickly to the end of the lane.

Ke is a preposition meaning to, toward, or in the direction of.

So:

• ke hujung lorong = to the end of the lane

This shows movement toward a destination.

Compare:

• di hujung lorong = at the end of the lane
• ke hujung lorong = to the end of the lane

It means the end of the lane/alley/corridor.

Breaking it down:

• hujung = end, tip
• lorong = lane, alley, passage, corridor depending on context

So:

• hujung lorong = the end of the lane

Malay often links nouns directly like this without using of.

Malay does not have articles like a, an, and the in the same way English does.

Whether something is definite or indefinite is usually understood from context.

So:

• seorang lelaki = a man
• hujung lorong = the end of the lane / an end of a lane, depending on context

In this sentence, English naturally uses the end of the lane, even though Malay does not need a separate word for the.

The comma is not strictly required in all writing, but it is helpful.

It marks the opening scene-setting phrase:

• Dari balkoni pangsapuri itu, ...

This makes it easier to read and shows that the phrase gives the viewpoint or location before the main clause begins.

Without the comma, the sentence would still be understandable.

Yes. Both are natural English translations.

• From the balcony of that apartment is more explicit
• From that apartment balcony is more compact and natural in some contexts

Both reflect the Malay phrase Dari balkoni pangsapuri itu.
