Saya memesan makanan dari restoran dekat kantor, lalu menyimpan sisanya untuk camilan nanti.

Memesan is the verb form built from the root pesan, which can relate to ordering or booking.

• pesan = the root word
• memesan = to order

In full, standard Indonesian, the meN- prefix often marks an active verb. So:

• Saya memesan makanan = I ordered food / I order food

In casual speech, Indonesians sometimes do say Saya pesan makanan, especially in conversation, but memesan sounds more standard and grammatically complete.

No. Memesan has a broader meaning: to order, to book, or to reserve, depending on context.

Examples:

• memesan makanan = order food
• memesan tiket = book tickets
• memesan kamar hotel = reserve a hotel room

So the verb itself is flexible; the object tells you what kind of ordering is happening.

Yes. Here dari means from, showing the source of the food.

• makanan dari restoran dekat kantor = food from the restaurant near the office

It tells you where the food came from. In English, from works the same way.

A learner might wonder whether this means physically moving from the restaurant. It can, but more generally it just marks origin or source.

Both are possible, but restoran dekat kantor is a shorter and very natural way to say the restaurant near the office.

• restoran dekat kantor = restaurant near the office
• restoran yang dekat kantor = restaurant that is near the office

Indonesian often omits yang when the meaning is already clear and the phrase is simple. So restoran dekat kantor sounds efficient and natural.

Indonesian does not use articles like the and a/an the way English does.

So:

• restoran can mean a restaurant or the restaurant
• kantor can mean an office, the office, or sometimes office in a general sense

Context tells you which meaning is intended. In this sentence, English would naturally translate it as the restaurant near the office, but Indonesian does not need a separate word for the.

Lalu means something like then, after that, or and then. It connects actions in sequence.

• Saya memesan makanan ..., lalu menyimpan sisanya ... = I ordered food ..., then saved the rest ...

By contrast, dan simply means and and does not emphasize sequence as strongly.

So:

• dan = adds another idea
• lalu = shows the next step

In this sentence, lalu is used because the person first ordered food, and after that saved the remainder.

The base word is simpan, which means to store, to keep, or to save.

With the meN- prefix, it becomes menyimpan, the active verb form.

• simpan = store/keep/save
• menyimpan = to store / to keep / to save

The spelling changes because Indonesian prefixes often adjust depending on the first sound of the root word. With simpan, the s changes in this pattern, giving menyimpan.

Sisanya means the rest, the remainder, or what was left over.

It comes from:

• sisa = remainder, leftover
• -nya = here it makes it mean something like the remaining part of it

So:

• menyimpan sisanya = save the rest
• in context, this often implies save the leftovers

Important point: -nya here does not necessarily mean his/her. It often points to something already understood from context. In this sentence, sisanya refers to the rest of the food.

Often yes in this kind of sentence, but not always exactly.

• sisa = whatever remains
• leftovers in English usually specifically means leftover food

Because the sentence is about food, sisanya can naturally be understood as the leftovers. But in a different context, sisa could refer to any remaining amount, not just food.

For example:

• sisanya uang saya = the rest of my money
• sisanya pekerjaan = the rest of the work

Indonesian often uses compact noun phrases where English might prefer a longer expression.

• untuk = for
• camilan = snack
• nanti = later

So untuk camilan nanti literally looks like for a snack later, but the natural meaning is to eat as a snack later or for later snacking.

The verb does not need to be stated because the purpose is already obvious from context.

Camilan is a noun, meaning snack.

It refers to the food itself, not the action. So:

• camilan = a snack / snack food

If you want the idea of to snack, Indonesian often uses verbs like:

• ngemil = to snack casually
• mencamil = to nibble / snack

In this sentence, camilan is used as a noun in a purpose phrase:

• untuk camilan nanti = for a snack later

Nanti usually means later, but its exact sense depends on context. It can mean:

• later today
• after this
• sometime in the future

In this sentence, untuk camilan nanti means the speaker plans to eat it at a later time, probably later that day.

So nanti is a flexible time word, and context tells you how far in the future it is.

You are noticing an important feature of Indonesian: verbs do not change form for tense the way English verbs do.

• Saya memesan can mean I order or I ordered
• menyimpan can mean save, saved, am saving, depending on context

Time is usually understood from:

• context
• time words such as kemarin, tadi, besok, nanti
• the overall situation

In this sentence, the sequence suggests a completed action, so English often translates it in the past: I ordered food ..., then saved the rest .... But the Indonesian verb itself does not mark past tense.

Yes, in some contexts, especially in conversation, it could be omitted if the subject is already clear.

For example:

• Memesan makanan dari restoran dekat kantor, lalu menyimpan sisanya untuk camilan nanti.

This can sound natural in informal speech or writing when the speaker is obvious from context. However, including Saya makes the sentence clearer and more complete, especially for standard written Indonesian.

Yes, it is natural and correct. A native speaker might still choose slightly different wording depending on formality.

Possible variations:

• Saya pesan makanan dari restoran dekat kantor, lalu simpan sisanya buat camilan nanti.
  More casual.
• Saya memesan makanan dari restoran yang dekat kantor, lalu menyimpan sisanya untuk dimakan nanti.
  Slightly more explicit.

Your original sentence sounds clear, grammatical, and natural in standard Indonesian.
