Dia menghayun raket itu dengan hayunan cepat.

In Malay, dia is normally gender-neutral. It can mean he or she, and the sentence itself does not specify which one.

So:

• Dia menghayun raket itu... = He swung that racket... or She swung that racket...

If Malay needs to make gender clear, it usually does so through context or by adding a noun such as:

• lelaki itu = the man
• perempuan itu = the woman

Menghayun comes from the root hayun, which is related to swinging.

The prefix meng- is a very common Malay verb-forming prefix. It often creates an active verb, especially when someone is doing an action to something.

So here:

• hayun = swing
• menghayun = to swing / to swing something

In this sentence, Dia menghayun raket itu means that the person performed the action of swinging the racket.

Yes. In this sentence, menghayun is being used transitively, meaning the action is directed at an object.

The object is:

• raket itu = that racket / the racket

So the structure is:

• Dia = subject
• menghayun = verb
• raket itu = object

That gives: Dia menghayun raket itu = He/She swung the racket.

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

So:

• raket ini = this racket
• raket itu = that racket

This is the normal Malay word order.

Depending on context, raket itu can mean:

• that racket
• the racket

So although itu literally points to that, in many sentences it also helps make the noun sound definite, similar to the in English.

Dengan often means with, using, or sometimes in a ... manner.

Here, it introduces the way the action was done:

• dengan hayunan cepat = with a quick swing

So it is not marking a separate object. It is describing how the racket was swung.

Common uses of dengan include:

• dengan tangan = with the hand
• dengan pisau = with a knife
• dengan cepat = quickly

In Malay, adjectives usually come after the noun they describe.

So:

• hayunan cepat = a quick swing
• rumah besar = a big house
• budak kecil = a small child

That is why cepat comes after hayunan, not before it.

They come from the same root, hayun, but they are playing different roles.

• menghayun = a verb: to swing
• hayunan = a noun: a swing, a swinging motion

So the sentence literally has something like:

• He/She swung the racket with a quick swing

This kind of root repetition is possible in Malay because different affixes create different parts of speech.

It is understandable, but it can sound a bit formal, descriptive, or slightly literary.

In everyday speech, many speakers would more naturally say:

• Dia menghayun raket itu dengan cepat. = He/She swung the racket quickly.

That version is simpler because it uses the adverbial phrase dengan cepat instead of the noun phrase dengan hayunan cepat.

So:

• dengan hayunan cepat = with a quick swing
• dengan cepat = quickly

Both are possible, but the second is usually more natural in ordinary conversation.

Yes, you may also encounter menghayunkan.

Malay sometimes uses both forms depending on style and nuance:

• menghayun raket
• menghayunkan raket

Both can refer to swinging the racket. In many learning situations, it is enough to recognize that both are related to the action of swinging. The version in your sentence, menghayun, is acceptable and straightforward.

Malay words are often more flexible than English words.

Cepat can mean:

• fast / quick as an adjective
• quickly / fast in an adverb-like function

In this sentence, inside hayunan cepat, it is describing the noun hayunan, so it works like an adjective:

• a quick swing

In a sentence like:

• Dia berlari cepat. = He/She runs fast.

it behaves more like an adverb in English translation.

The sentence follows a very common Malay pattern:

• Dia = subject
• menghayun = verb
• raket itu = object
• dengan hayunan cepat = adverbial/prepositional phrase describing manner

So the structure is:

Subject + Verb + Object + Manner phrase

That is a very normal Malay sentence pattern.

Malay does not have articles exactly like English a/an and the.

Instead, definiteness is often understood from:

• context
• word order
• demonstratives like ini and itu

In this sentence:

• raket itu often feels like that racket or the racket
• hayunan cepat can feel like a quick swing or simply quick swinging, depending on context

So Malay usually leaves that interpretation to context rather than requiring an article every time.

A very learner-friendly, natural version would be:

• Dia menghayun raket itu dengan cepat.

That keeps the same basic meaning but is easier because:

• menghayun = swing
• raket itu = the/that racket
• dengan cepat = quickly

So if dengan hayunan cepat feels heavy or unusual at first, dengan cepat is a very good alternative to learn and use.
