Teman saya terlalu ngotot, padahal keputusan itu sudah jelas.

Ngotot means something like to insist stubbornly, to keep pushing your point, or to refuse to back down.

In this sentence, terlalu ngotot suggests that the friend is being excessively stubborn or pushy about the matter.

It has a conversational feel and often carries a mildly negative judgment.

No, ngotot is fairly informal/colloquial. It is very common in everyday speech and informal writing.

In more formal Indonesian, people might choose words like:

• bersikeras = to insist
• keras kepala = stubborn
• memaksakan pendapat = to force one’s opinion

But ngotot is natural and common in normal conversation.

Terlalu means too or excessively.

So:

• ngotot = stubbornly insisting
• terlalu ngotot = too stubborn / too insistent

It shows that the speaker thinks the behavior goes beyond what is reasonable.

This is different from:

• sangat ngotot = very insistent
• terlalu ngotot = too insistent, with a negative sense

Padahal introduces a contrast between reality and someone’s behavior, or between what is true and what someone is doing.

Here it means something like:

• even though
• when in fact
• despite the fact that
• whereas actually

So the logic is:

• Teman saya terlalu ngotot = My friend is being too stubborn/insistent
• padahal keputusan itu sudah jelas = even though the decision is already clear

It often implies that the first part is unreasonable in light of the second part.

No. Sudah does not simply mark past tense the way English does. It usually indicates that a state or action is already completed or already in effect.

So keputusan itu sudah jelas means:

• the decision is already clear
• the decision has become clear
• the decision is clearly settled

In Indonesian, sudah often focuses on the status of something, not just when it happened.

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

So:

• keputusan itu = that decision / the decision
• teman itu = that friend
• rumah itu = that house

Putting itu after the noun is the normal pattern.

In this sentence, keputusan itu can mean either:

• that decision
• or the decision, depending on context

Both are possible.

• teman saya = my friend
• temanku = my friend

The difference is mainly one of style and register:

• teman saya sounds a bit more neutral and standard
• temanku sounds a bit more casual and personal

In many contexts, both are completely natural.

Yes, jelas can mean both clear and obvious, depending on context.

In keputusan itu sudah jelas, it often feels closer to:

• the decision is already clear
• the decision is obvious
• the matter has already been settled clearly

So jelas is broader than just visual or literal clarity.

Yes, at least somewhat.

Several parts contribute to that feeling:

• terlalu gives criticism
• ngotot is slightly negative
• padahal adds a sense of but that makes no sense, because...

So the sentence sounds like the speaker thinks the friend is being unreasonable.

A more formal version could be:

Teman saya terlalu bersikeras, padahal keputusan itu sudah jelas.

or

Teman saya bersikeras, padahal keputusan itu sudah jelas.

Notes:

• bersikeras is more formal than ngotot
• removing terlalu makes it a little less emotionally critical

The original sentence is more natural in everyday spoken Indonesian.

The ng in ngotot is the same sound as the end of English sing, but in Indonesian it can appear at the beginning of a word.

So ngotot begins directly with that ng sound:

• ngo-tot

A good way to practice is:

1. Say the end of sing
2. Hold the ng sound
3. Then add o-tot

So it becomes ng-o-tot.

This beginning ng is very common in Indonesian.

Not exactly.

• tetapi = but
• padahal = even though / whereas actually / when in fact

If you say:

Teman saya terlalu ngotot, tetapi keputusan itu sudah jelas

it is understandable, but it sounds less natural and weaker in meaning.

Padahal is better because it highlights that the second clause makes the first clause seem unreasonable.

The structure is:

• Teman saya = subject noun phrase
• terlalu ngotot = predicate/adjective-like description
• padahal keputusan itu sudah jelas = contrasting clause

So literally it is:

• My friend
  • is too insistent/stubborn
• even though
  • that/the decision
    • is already clear

Indonesian often does not need a word like is in the same way English does, so terlalu ngotot and sudah jelas work directly as predicates.
