Saya beri kupon diskaun itu kepada ibu sebelum dia bayar di kaunter.

Both are possible, but they differ in style and register.

• beri is the shorter, more conversational form.
• memberi is the fuller, more formal form.

So:

• Saya beri kupon diskaun itu... = natural in everyday speech/writing
• Saya memberi kupon diskaun itu... = more formal, more written, or more careful style

Malay often allows this kind of shorter verb in ordinary usage.

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

So beri can mean:

• give
• gave
• will give

The time is understood from:

• context
• time words
• surrounding events

In this sentence, sebelum dia bayar di kaunter makes it clear that the giving happened before the payment, so English naturally translates it in the past if the context is past.

Itu means that, and here it works like a demonstrative placed after the noun.

So:

• kupon diskaun = discount coupon
• kupon diskaun itu = that discount coupon / the discount coupon

This is a common Malay pattern:

• buku itu = that book
• rumah itu = that house

Unlike English, the demonstrative usually comes after the noun, not before it.

Kepada marks the recipient of the action, similar to to in English.

So:

• Saya beri kupon diskaun itu kepada ibu = I gave the discount coupon to mother

This is especially common when the recipient is a person.

You may also hear saya beri ibu kupon diskaun itu, especially in speech, but kepada ibu is clear and very standard.

Malay often leaves out possessive words like my, your, or his/her when the meaning is already obvious from context.

So ibu can mean:

• mother
• my mother
• mom

depending on the situation.

In this sentence, because the speaker says saya and the situation is personal, ibu is very naturally understood as my mother.

If needed, Malay can be more explicit:

• ibu saya = my mother

But it is often not necessary.

Dia means he or she. Malay usually does not distinguish gender in third-person singular pronouns.

In this sentence, dia most likely refers back to ibu.

So:

• sebelum dia bayar di kaunter = before she paid at the counter

Malay relies on context to tell you who dia is.

This is similar to beri/memberi.

• bayar = shorter, less formal, very common
• membayar = more formal or more complete form

So both are possible:

• sebelum dia bayar di kaunter
• sebelum dia membayar di kaunter

The version with bayar sounds very natural in everyday Malay.

Sebelum means before and introduces the event that happens later in the sequence.

So the order is:

1. Saya beri kupon diskaun itu kepada ibu
2. dia bayar di kaunter

That means the coupon was given before the payment at the counter.

Malay uses sebelum very straightforwardly, much like English before.

Di is a preposition meaning at / in / on, and kaunter means counter.

So:

• di kaunter = at the counter

It is written as two words because this di is a preposition.

This is important because Malay also has a prefix di- used for passive verbs, and that one is written together:

• dibayar = paid
• ditulis = written

But here it is a location phrase, so it must be separate:

• di kaunter
• di rumah
• di sekolah

Yes, it is very normal. The structure is:

• Saya = subject
• beri = verb
• kupon diskaun itu = object
• kepada ibu = recipient
• sebelum dia bayar di kaunter = time clause

So the sentence flows naturally as:

Subject + Verb + Object + Recipient + Time clause

This is a common and natural Malay sentence pattern.

Yes. Here are a few natural alternatives, with slightly different style or emphasis:

• Saya beri ibu kupon diskaun itu sebelum dia bayar di kaunter.
  More direct, without kepada

• Saya memberikan kupon diskaun itu kepada ibu sebelum dia membayar di kaunter.
  More formal

• Sebelum ibu bayar di kaunter, saya beri kupon diskaun itu kepadanya.
  Starts with the time clause instead

All of these are understandable; the original sentence is already perfectly natural.

It is normal and understandable Malay, but both words are loanwords or heavily influenced by English usage.

• kupon = coupon
• diskaun = discount

Malay uses many borrowed words, especially in shopping, business, and modern daily life. So kupon diskaun is a very normal expression in real usage.

You might also hear related expressions such as:

• baucar diskaun = discount voucher
• kupon potongan harga = discount coupon, with a more Malay-style phrase for discount

But kupon diskaun is completely natural.
