-려고 expresses purpose or intention: in order to, so that, with the intention of.

So 안 잃어버리려고 means in order not to lose it.

In this sentence, the first part explains why the speaker did the second action:

• 처방전을 안 잃어버리려고 = in order not to lose the prescription
• 약봉지를 가방 안에 바로 넣었어 = I put the medicine bag straight into my bag

So the structure is basically:

[reason/purpose] + [main action]

Both are possible.

• 안 잃어버리려고 = shorter, more conversational
• 잃어버리지 않으려고 = longer, slightly more formal or careful

For many everyday verbs, Korean often uses 안 + verb in speech because it is simpler and very natural.

So:

• 안 잃어버리려고
• 잃어버리지 않으려고

both mean in order not to lose.

A learner should know that 안 usually goes before the verb phrase, while -지 않다 attaches to the verb stem.

잃다 means to lose.

잃어버리다 also means to lose, but it often adds a stronger feeling that something was lost completely, misplaced, or lost unfortunately.

So:

• 잃다 = lose
• 잃어버리다 = lose/misplace, often with a sense of oops, it’s gone

In everyday Korean, 잃어버리다 is very common when talking about losing objects like keys, a wallet, a phone, or a document.

Here, 처방전을 안 잃어버리려고 sounds very natural because a prescription is the kind of thing you might accidentally misplace.

Yes. That is completely normal here because the sentence has two different verbs/clause parts.

• 처방전을 belongs with 안 잃어버리려고
• 약봉지를 belongs with 넣었어

So this is not one verb taking two objects. It is more like:

• 처방전을 안 잃어버리려고 = in order not to lose the prescription
• 약봉지를 가방 안에 바로 넣었어 = I put the medicine bag right into the bag

Each verb has its own object:

• 잃어버리다 → 처방전
• 넣다 → 약봉지

That is why both 처방전을 and 약봉지를 appear with -을/를.

Because 넣다 is a verb of putting something into a place, so Korean uses 에 to mark the destination.

• 가방 안에 넣다 = put it inside the bag

If you used 에서, it would usually mark the place where an action happens, not the place something is being put into.

Compare:

• 가방 안에 넣었어 = put it inside the bag
• 가방 안에서 찾았어 = found it inside the bag

So with 넣다, 에 is the natural choice.

안 means inside or the interior.

With the location particle 에, it becomes 안에 = inside / in.

So:

• 가방 = bag
• 가방 안 = the inside of the bag
• 가방 안에 = inside the bag

This is a very common pattern:

• 상자 안에 = inside the box
• 집 안에 = inside the house
• 서랍 안에 = inside the drawer

Here, 바로 means something like right away, immediately, or directly.

In this sentence, it gives the feeling that the speaker did not leave the medicine bag lying around, but put it straight into the bag at once.

Depending on context, 바로 can mean slightly different things:

• right away / immediately
• directly
• right / exactly

In this sentence, the most natural sense is right away / straight away.

Yes. Korean adverbs are often fairly flexible.

For example, these are all possible with only small differences in emphasis:

• 약봉지를 가방 안에 바로 넣었어
• 약봉지를 바로 가방 안에 넣었어
• 바로 약봉지를 가방 안에 넣었어

The basic meaning stays similar, but the focus shifts a little:

• 가방 안에 바로 넣었어 can emphasize the act of putting it there immediately
• 바로 가방 안에 can emphasize that it went straight into the bag
• 바로 약봉지를 can emphasize the medicine bag itself as the thing immediately handled

Korean word order is more flexible than English, especially with adverbs.

넣었어 is:

• 넣다 = to put
• 넣었- = past tense
• -어 = casual speech ending

So 넣었어 means put or I put it in a casual, informal style.

This kind of ending is used when speaking to:

• friends
• close family
• younger people
• someone you are on casual terms with

More polite versions would be:

• 넣었어요 = polite
• 넣었습니다 = formal

Korean often omits the subject when it is already understood from context.

So even though the sentence does not explicitly say I, English usually translates it that way because the context makes it obvious.

Korean speakers often leave out:

• I
• you
• he/she
• sometimes even objects

if they are clear from the situation.

So this sentence naturally sounds like:

• (나는) 처방전을 안 잃어버리려고 약봉지를 가방 안에 바로 넣었어.

But 나는 is unnecessary unless the speaker wants to emphasize I.

Yes.

• 처방전 = prescription, usually the paper/document from the doctor
• 약봉지 = medicine bag, medicine packet, or medicine envelope/package from the pharmacy

A learner may notice that the sentence says the speaker put the medicine bag into the bag, even though the thing they did not want to lose was the prescription.

That can still make sense contextually. For example:

• the prescription may have been together with the medicine
• the speaker may have put the whole pharmacy package away to keep everything together
• the practical point is that they stored the related items safely

So the sentence is natural even if the two nouns are not the same object.

Yes, but the nuance changes slightly because the verb changes.

• 잃어버리다 = lose/misplace completely
• 잃다 = lose

So:

• 안 잃어버리려고 = in order not to lose/misplace it
• 잃지 않으려고 = in order not to lose it

Both are grammatical, but 잃어버리다 often sounds more natural for accidentally misplacing a physical item like a prescription.

Also, 잃지 않으려고 sounds a bit more neutral or bookish than the everyday 안 잃어버리려고.

Yes, but 가방 안에 is more specific.

• 가방에 넣었어 = put it in the bag
• 가방 안에 넣었어 = put it inside the bag

In many situations, 가방에 already implies inside the bag, so it is often enough.

But 가방 안에 makes the image more explicit and can emphasize that it was put safely inside, not just onto or around the bag.

Yes. It is a very common and natural pattern:

[object] + 안/못 + verb-려고 + [main action]

Examples:

• 핸드폰을 안 잃어버리려고 주머니에 넣었어.
  = I put my phone in my pocket so I wouldn’t lose it.

• 늦지 않으려고 일찍 나왔어.
  = I left early so I wouldn’t be late.

• 까먹지 않으려고 메모했어.
  = I wrote it down so I wouldn’t forget.

So this sentence is a great example of how Korean expresses doing one action for the purpose of preventing a problem.
