Lecet di tumit saya masih sakit, jadi saya jalan pelan-pelan.

Lecet usually refers to a scrape, abrasion, or raw/chafed spot on the skin. In everyday context, it can also overlap with the idea of a small blistered or rubbed sore area, especially on the foot.

So in this sentence, lecet di tumit saya means something like the scrape / rubbed sore spot on my heel.

Both patterns are possible, but they focus on things a little differently.

• Tumit saya lecet = My heel is scraped/chafed.
• Lecet di tumit saya = The scrape/on my heel or the sore spot on my heel

In your sentence, lecet is being treated more like a thing: the injury itself is what still hurts.

So:

• Lecet di tumit saya masih sakit
  = The scrape on my heel still hurts

This is very natural Indonesian.

Here, di means on, at, or in depending on context. It marks location.

So:

• di tumit saya = on my heel

A very literal breakdown is:

• lecet = scrape / sore spot
• di tumit saya = on my heel

So together: the scrape on my heel.

In Indonesian, possession is commonly shown by putting the possessor after the noun.

So:

• tumit saya = my heel
• literally: heel my

This is normal Indonesian word order.

Other examples:

• rumah saya = my house
• buku saya = my book
• kaki saya = my foot/leg

Masih means still.

So:

• masih sakit = still hurts / is still painful

It shows that the pain has continued and has not gone away yet.

Other examples:

• Saya masih capek. = I’m still tired.
• Dia masih tidur. = He/She is still sleeping.

Sakit can cover several related meanings depending on context:

• sick / ill
• painful
• to hurt

In this sentence, sakit means painful or hurts.

So:

• Lecet di tumit saya masih sakit = The scrape on my heel still hurts

This is a very common feature of Indonesian: one word can match several English words depending on context.

Compare:

• Saya sakit. = I’m sick.
• Kaki saya sakit. = My leg/foot hurts.
• Luka itu sakit. = That wound is painful / hurts.

Jadi here means so, therefore, or as a result.

It connects the first idea to the result:

• My heel still hurts, so I walk slowly.

In other contexts, jadi can also mean become, which is a very common source of confusion for learners.

For example:

• Dia jadi marah. = He/She became angry.

But in your sentence, it clearly means so.

In everyday Indonesian, jalan is very commonly used as a verb meaning to walk.

So:

• saya jalan = I walk / I’m walking

The form berjalan is also correct, but it is often a bit more formal, careful, or neutral.

Compare:

• Saya jalan pelan-pelan. = natural everyday speech
• Saya berjalan pelan-pelan. = also correct, slightly more formal

So the sentence sounds natural and conversational.

This is reduplication, which is very common in Indonesian.

Pelan means slow or soft/gently, and pelan-pelan means slowly or carefully/at a slow pace.

In this sentence:

• jalan pelan-pelan = walk slowly

Reduplication often makes an expression sound more natural or gives an adverb-like meaning.

Other examples:

• baik-baik = carefully / properly
• pelan-pelan = slowly
• hati-hati = be careful

Yes. That would be understandable and correct.

Possible versions:

• Saya jalan pelan-pelan.
• Saya berjalan pelan-pelan.
• Saya berjalan pelan.

However, pelan-pelan sounds especially natural in everyday speech for slowly.

So your original sentence is a very normal way to say it.

Grammatically, the subject is lecet di tumit saya — in other words, the scrape/chafed spot on my heel.

So the sentence is saying that the injury itself still hurts.

That is why the structure is:

• Lecet di tumit saya = the scrape on my heel
• masih sakit = still hurts

A very literal translation would be:

• The scrape on my heel still hurts, so I walk slowly.

That is already fairly natural English. But depending on context, a smoother English translation might be:

• The scrape on my heel still hurts, so I’m walking slowly.
• My heel is still sore, so I’m walking slowly.

The Indonesian sentence itself is natural and straightforward.

It is neutral and natural, leaning a bit toward everyday spoken Indonesian because of jalan instead of berjalan.

Nothing in it is slang. It would be fine in normal conversation.

If you wanted to make it a bit more formal, you could say:

• Lecet di tumit saya masih sakit, jadi saya berjalan pelan-pelan.

But the original sentence is completely standard and natural.
