Saya lupa kod itu.

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

So lupa can mean:

• forget
• forgot
• have forgotten

The time is usually understood from context. If you want to make the past meaning clearer, you can add words like:

• Saya sudah lupa kod itu. = I have already forgotten that code.
• Saya terlupa kod itu tadi. = I forgot that code earlier.

So Saya lupa kod itu is completely normal even when English uses forgot.

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

So:

• kod ini = this code
• kod itu = that code

This is different from English, where this and that come before the noun.

So kod itu is the natural Malay order, not itu kod in this sentence.

It can often feel like either, depending on context.

Literally:

• kod itu = that code

But in real usage, it can also function like:

• the code
• that specific code we both know about

Malay does not have a direct equivalent of English the. Very often, definiteness is understood from context, and itu can help make the noun sound more specific.

Yes.

The difference is mainly register and social tone:

• Saya = neutral, polite, standard
• Aku = informal, casual, more personal

So:

• Saya lupa kod itu. sounds safe and standard.
• Aku lupa kod itu. sounds more casual, like talking to friends or people you are close to.

If you are unsure, saya is the better default.

Usually, no.

In everyday modern Malay, you normally say:

• Saya lupa kod itu.

This is the most natural structure:
subject + lupa + object

You may sometimes see lupa akan, especially in more formal or literary language:

• Saya lupa akan kod itu.

But this is less common in ordinary conversation. For most learners, using lupa directly with the noun is the best choice.

Both can be translated as forget/forgot, but terlupa often suggests that it happened unintentionally or that something slipped your mind.

Compare:

• Saya lupa kod itu. = I forgot that code.
• Saya terlupa kod itu. = I forgot that code / It slipped my mind.

In many situations, they overlap. But terlupa can sound a little more like an accidental lapse.

Yes, but the default and most neutral order is:

• Saya lupa kod itu.

If you say:

• Kod itu saya lupa.

that puts extra focus on kod itu, like:

• That code, I forgot.
• It was that code that I forgot.

So the changed order is possible, but it is more marked or emphatic.

You can say:

• Saya tidak lupa kod itu. = I did not forget that code.
• Saya tak lupa kod itu. = same meaning, but more informal

Here:

• tidak = standard/formal not
• tak = casual spoken contraction

It is a standard Malay word, but yes, it is a loanword from English code.

Malay uses many loanwords, especially for modern or technical vocabulary. Kod is fully normal in Malay.

You may also see it in compounds such as:

• kod laluan = password/passcode
• kod QR = QR code
• kod warna = color code

A simple learner-friendly pronunciation is:

sah-yuh loo-pah kod ee-too

A few helpful notes:

• saya is often pronounced more casually like saye in speech
• lupa has clear vowels: lu-pa
• itu is ee-too
• kod is usually pronounced close to how it is spelled, with a final d that may sound light

So in natural speech, it may sound something like:

saye lupa kod tu

because itu is often shortened to tu in casual spoken Malay.
