Penyewa ini tentu membayar sewa bulanan.

In Malay, demonstratives usually come after the noun:

• penyewa ini = this tenant
• penyewa itu = that tenant

So this is normal Malay word order. English says this tenant, but Malay says tenant this.

Tentu means something like certainly, surely, or definitely.

In this sentence, it adds a sense of confidence or certainty:

• Penyewa ini membayar sewa bulanan = This tenant pays monthly rent.
• Penyewa ini tentu membayar sewa bulanan = This tenant certainly/surely pays monthly rent.

Depending on context, tentu can sometimes sound like a confident assumption rather than an absolute fact.

Membayar is the standard active verb form of bayar (to pay).

• bayar = base/root form
• membayar = to pay / pays / paying

The prefix mem- is part of the common meN- verb pattern in Malay. In casual speech, people sometimes use the shorter root form, but membayar is more complete and standard in formal or careful Malay.

They are related, but they are not the same word class.

• sewa = rent, rental, hire
• penyewa = tenant / renter

So:

• penyewa is the person
• sewa is the rent or the act/concept of renting

This is why the sentence can contain both:

• Penyewa = the tenant
• membayar sewa = pays rent

Penyewa is built from the root sewa.

A simplified explanation:

• sewa = rent / to rent
• peN-
  • sewa → penyewa

This peN- pattern often creates a noun for the person who does something. So penyewa means the person who rents, that is, tenant/renter.

You do not need to memorize all the sound changes at once, but it is useful to notice that Malay often builds related words this way.

Malay normally puts modifiers after the noun.

So:

• sewa bulanan = monthly rent
• literally: rent monthly

This is very common in Malay:

• rumah besar = big house
• bayaran bulanan = monthly payment
• sewa bulanan = monthly rent

English usually puts many modifiers before the noun, but Malay often places them after it.

Bulanan means monthly.

It comes from:

• bulan = month
• bulanan = monthly / every month / relating to a month

So sewa bulanan means monthly rent, rent that is paid on a monthly basis.

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

So membayar by itself does not specifically mark:

• present
• past
• future

The time meaning comes from context. In this sentence, because of sewa bulanan, the most natural reading is a habitual/general one:

• This tenant certainly pays monthly rent
• or This tenant certainly pays the rent every month

If the context were different, Malay could make the time clearer with extra words such as sudah (already), akan (will), or sedang (in the process of).

Malay does not normally use articles like English a, an, and the.

So penyewa can mean:

• a tenant
• the tenant

And sewa bulanan can mean:

• monthly rent
• the monthly rent

The exact meaning depends on context. In this sentence, ini helps make penyewa ini specific, so it clearly means this tenant.

Yes. The sentence follows a very natural Malay pattern:

• Penyewa ini = subject
• tentu = adverb expressing certainty
• membayar = verb
• sewa bulanan = object

So the structure is basically:

Subject + certainty word + verb + object

That makes the sentence straightforward and natural in standard Malay.
