Sejauh mana pun wakil itu pergi, proksi tetap sah.

It is a concessive expression meaning no matter how far or however far.

A helpful breakdown is:

• jauh = far
• sejauh mana = how far / to what extent
• pun = adds the sense of no matter / even

So sejauh mana pun wakil itu pergi is not a question here. It functions like an introductory clause meaning however far the representative goes.

pun adds a meaning like regardless, even, or no matter.

Without pun, sejauh mana is more like how far or to what extent, which can sound like a question phrase.

With pun:

• sejauh mana = how far / to what extent
• sejauh mana pun = no matter how far / however far

This is very common in Malay with question words or extent words:

• siapa pun = whoever / no matter who
• apa pun = whatever / no matter what
• di mana pun = wherever
• bila pun = whenever

So here, pun is the key word that turns the phrase into a concessive idea.

They are similar, but they focus on different things.

• sejauh mana pun focuses on distance or extent: no matter how far
• ke mana pun focuses on destination/place: wherever

So:

• Sejauh mana pun wakil itu pergi... = No matter how far the representative goes...
• Ke mana pun wakil itu pergi... = Wherever the representative goes...

In your sentence, the emphasis is on distance, not just location.

In Malay, demonstratives usually come after the noun.

So:

• wakil itu = that representative / the representative
• rumah itu = that house / the house
• orang itu = that person / the person

This is normal Malay word order. English puts that/the before the noun, but Malay often puts itu after it.

In many contexts, itu can sound like either that or simply the, depending on what sounds natural in English.

Yes, they are related, but they are not exactly the same in this sentence.

• wakil usually refers to a person acting on someone’s behalf: a representative, agent, delegate
• proksi usually refers to the proxy status/authority/arrangement, especially in formal or legal contexts

So in this sentence:

• wakil itu = the representative person
• proksi = the proxy authorization or proxy standing

That is why both can appear in the same sentence without being redundant. One is the person, and the other is the legal/formal validity of the proxy.

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

So pergi can mean:

• go
• goes
• went
• gone

The time reference is usually understood from context, time words, or the general meaning of the sentence.

Here the sentence states a general rule or continuing fact, so English naturally uses the present tense:

• wakil itu pergi → the representative goes

If the context were past, English might translate it differently, but the Malay verb itself stays the same.

tetap sah means something like remains valid, stays valid, or is still valid.

Breakdown:

• tetap = still, remains, continues to be
• sah = valid, legitimate, legally valid

Malay often uses this kind of structure very directly:

• tetap sah
• literally: still valid
• naturally in English: remains valid

So there is no separate verb exactly matching English remain. The meaning comes from tetap plus the adjective sah.

Not only, but it is very common in formal, legal, administrative, and official contexts.

sah can mean:

• valid
• official
• legitimate
• lawful

Examples:

• dokumen itu sah = the document is valid
• perkahwinan itu sah = the marriage is valid/legal
• undi sah = a valid vote

In your sentence, sah fits well because proksi sounds formal and administrative.

Because in this sentence, pun is functioning as a separate particle.

So Malay writes:

• siapa pun
• apa pun
• mana pun
• sejauh mana pun

However, some words with pun have become fixed spellings and are written as one word, such as:

• walaupun
• meskipun
• adapun

So sejauh mana pun is correct with pun written separately.

The comma is not absolutely required in every informal context, but it is very helpful here because the sentence begins with a subordinate concessive clause.

So this is clear and natural:

• Sejauh mana pun wakil itu pergi, proksi tetap sah.

The order can also be reversed:

• Proksi tetap sah sejauh mana pun wakil itu pergi.

Both are grammatical, but the original version is often easier to read because it clearly separates:

1. the condition/concession
2. the main statement

Yes. Malay often allows a fuller version such as:

• Walau sejauh mana pun wakil itu pergi, proksi tetap sah.
• Meski sejauh mana pun wakil itu pergi, proksi tetap sah.

These make the concessive meaning even more explicit, like even no matter how far or although however far.

But in your sentence, sejauh mana pun already carries that meaning well, so walau or meski is optional rather than necessary.
