Dia boleh bernafas seperti biasa lagi.

Yes. Dia can mean he or she. Malay does not normally mark gender in third-person singular pronouns the way English does.

So:

• Dia = he / she
• sometimes, depending on context, it can also be understood more generally as that person

You usually figure out the gender from context, earlier sentences, or real-world knowledge.

Here, boleh means can or is able to.

So in this sentence:

• Dia boleh bernafas... = He/She can breathe...

A useful point: boleh can also mean may / be allowed to in other contexts.

For example:

• Saya boleh masuk? = May I come in?
• Dia boleh berenang. = He/She can swim.

In your sentence, it clearly means ability, not permission.

Because nafas is the noun breath, while bernafas is the verb to breathe.

• nafas = breath
• bernafas = to breathe

The prefix ber- often turns a noun or base word into an intransitive verb, often meaning to have, to use, or to do something involving that thing.

So:

• nafas = breath
• bernafas = breathe

This is a very common Malay pattern.

In this sentence, ber- helps form the verb bernafas.

A simple learner-friendly way to think about ber- is:

• it often makes an intransitive verb
• it often means something like to have, to wear, to use, or to do

Examples:

• baju = shirt
  berbaju = wearing a shirt
• jalan = road / walk
  berjalan = to walk
• nafas = breath
  bernafas = to breathe

You do not usually break it apart when speaking; bernafas is treated as a normal verb.

Seperti biasa means as usual or like normal / normally.

Breakdown:

• seperti = like / as
• biasa = usual / normal / ordinary

So:

• seperti biasa = as usual
• in natural English here: normally

That is why the sentence means something like He/She can breathe normally again.

Yes, very often you can.

• seperti biasa = more standard / neutral / slightly more formal
• macam biasa = more conversational

So these are both natural:

• Dia boleh bernafas seperti biasa lagi.
• Dia boleh bernafas macam biasa lagi.

Both suggest can breathe normally again, though seperti sounds a bit more formal or careful.

Here, lagi means again.

So:

• Dia boleh bernafas seperti biasa lagi. = He/She can breathe normally again.

A very important learner point: lagi has several meanings depending on context, including:

• again
• more / additional / another
• in negative sentences, it can help mean no longer / no more

Examples:

• Cuba lagi. = Try again.
• Satu lagi. = One more / another one.
• Dia tidak datang lagi. = He/She is not coming anymore / no longer coming (depending on context)

So you should always read lagi from context.

Because in Malay, lagi often comes after the part it modifies, especially when it means again.

Here it naturally follows the whole idea:

• boleh bernafas seperti biasa lagi

This sounds like can breathe normally again.

Malay often places words like this after the verb phrase rather than before it, compared with English.

For example:

• Dia datang lagi. = He/She came again / is coming again.
• Saya cuba lagi. = I’ll try again.

So the final position is normal.

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

So bernafas stays bernafas whether the action is present, past, or future. Time is usually understood from context or from time words.

That means this sentence could fit different contexts, for example:

• Now she can breathe normally again.
• After the treatment, he could breathe normally again.
• Soon she will be able to breathe normally again.

If you want to make time clearer, Malay often adds words like:

• sudah / dah = already
• sedang = in progress
• akan = will
• semalam = yesterday
• esok = tomorrow

But this sentence by itself is tenseless.

Because Malay often does not need a verb equivalent to English is / am / are in the same way English does.

In this sentence, the main structure is:

• Dia = he/she
• boleh = can
• bernafas = breathe

Malay can directly say Dia boleh bernafas... without adding a separate word for is.

This is normal in Malay.

The basic order is:

• Dia = subject
• boleh = modal verb
• bernafas = main verb
• seperti biasa = adverbial phrase
• lagi = again

So:

Dia | boleh | bernafas | seperti biasa | lagi

A natural English-style breakdown would be:

He/She | can | breathe | normally / as usual | again

Malay word order here is quite close to English, except that lagi comes after the phrase it modifies.

Yes, that is possible, but the nuance can be a little different.

• boleh often focuses on can / be able to
• dapat often emphasizes manage to / succeed in / be able to

So both can work, but:

• Dia boleh bernafas seperti biasa lagi
  = He/She can breathe normally again
• Dia dapat bernafas seperti biasa lagi
  = He/She is able to / manages to breathe normally again

In many everyday contexts, they overlap. But boleh is a very common and straightforward choice here.

Yes, it is understandable and natural.

That said, depending on context, Malay speakers might also say things like:

• Dia boleh bernafas semula seperti biasa.
• Dia sudah boleh bernafas seperti biasa semula.

Here semula also means again / back to the previous state, and in recovery contexts it can sound especially natural.

Still, your original sentence is fine and clearly means that the person is able to breathe normally again.

A rough pronunciation guide is:

dee-yah boh-leh ber-nah-fahs se-per-tee bee-ah-sah lah-ghee

Very approximate notes:

• dia ≈ dee-yah
• boleh ≈ boh-leh
• bernafas ≈ ber-nah-fahs
• seperti ≈ se-per-tee
• biasa ≈ bee-ah-sah
• lagi ≈ lah-ghee

A couple of tips:

• r in Malay is usually tapped or lightly rolled
• vowels are generally clearer and more stable than in English
• Malay spelling is usually quite regular, so pronunciation is often more predictable than in English
