담배꽁초 means cigarette butt or cigarette end.

• 담배 = cigarette / tobacco
• 꽁초 = the stub or butt left over after something has been smoked

So 담배꽁초 is the leftover end of a cigarette after smoking.

는 is the topic particle. It marks 담배꽁초 as the thing being talked about: as for cigarette butts...

So the sentence has the feeling of:

• As for cigarette butts, put them in the regular trash sack.

If you used 를, it would focus more directly on cigarette butts as the object of the verb:

• 담배꽁초를 일반 쓰레기 마대에 넣습니다.

That would also be grammatical, but 는 often sounds more natural in signs, instructions, or category-based statements, especially when telling you how to sort or dispose of something.

일반 쓰레기 means general trash or regular garbage.

• 일반 = general, ordinary, regular
• 쓰레기 = trash, garbage

In contexts like trash sorting, Korean often contrasts:

• 일반 쓰레기 = regular trash
• 재활용 = recycling
• 음식물 쓰레기 = food waste

So here it means cigarette butts should go with the non-recyclable, regular trash.

마대 refers to a sack or large bag, often a sturdy collection bag used for trash.

It is not always exactly the same as a small household plastic bag. Depending on context, it can mean:

• a trash sack
• a collection sack
• a large disposal bag

So 일반 쓰레기 마대 means something like:

• the general trash sack
• the bag for regular waste

In natural English, you might translate it simply as trash bag, but 마대 itself suggests a somewhat sturdier or designated collection sack.

에 marks the destination or place something goes into.

With 넣다 (to put in / insert), Korean commonly uses:

• X에 넣다 = put something into X

So:

• 일반 쓰레기 마대에 = into the general trash sack

This is similar to how 에 is used for locations and endpoints.

넣습니다 is the formal polite form of 넣다, which means to put in, to place in, or to insert.

Even though it looks like a present-tense statement, Korean often uses this form for:

• instructions
• rules
• notices
• official guidance

So 넣습니다 here does not necessarily mean is putting in right now. It often means:

• Put it in
• It goes in
• Please place it in

This is very common on signs and sorting instructions.

Yes. Korean often leaves out subjects when they are obvious from context.

In a notice or instruction, the implied meaning is often:

• You should put cigarette butts in the regular trash sack or
• Cigarette butts go in the regular trash sack

So the sentence can be understood either as:

1. an instruction to the reader, or
2. a general sorting rule

Korean does not need to explicitly say you here.

The sentence follows normal Korean word order: topic + place/destination + verb

• 담배꽁초는 = as for cigarette butts
• 일반 쓰레기 마대에 = into the regular trash sack
• 넣습니다 = put / are put

So literally, it is something like:

• As for cigarette butts, into the general trash sack put (them).

Korean verbs usually come at the end of the sentence, which is one of the biggest differences from English.

Yes. Both are reasonable translations.

Because Korean often leaves out the subject and uses polite formal verb endings in notices, the sentence can sound like either:

• a command/instruction
• a general rule/classification

So depending on context, both of these work:

• Put cigarette butts in the regular trash bag.
• Cigarette butts go in the regular trash bag.

English chooses between them more explicitly than Korean sometimes does.

It can be understood as plural in a general sense, even though Korean nouns usually do not have separate singular/plural forms the way English does.

So 담배꽁초는 can mean:

• a cigarette butt, in a general category sense
• cigarette butts, as a type of waste

In a trash-sorting notice, English will usually translate it as cigarette butts.

A natural pronunciation is approximately:

• 담배꽁초는 → dam-bae-kkong-cho-neun
• 일반 쓰레기 → il-ban sseu-re-gi
• 마대에 → ma-dae-e
• 넣습니다 → roughly neo-seum-ni-da

A few pronunciation notes:

• 꽁 has a tense ㄲ, so it is stronger than plain ㄱ
• 쓰 in 쓰레기 has tense ㅆ
• In 넣습니다, the pronunciation changes due to sound rules, so it does not sound exactly like each letter separately

You do not need perfect phonological analysis at the beginner stage, but it is good to know that spoken Korean often differs a bit from the spelling.
