In Korean, when you have a combined time phrase like Thursday night, it is very common to put 에 only once at the end:

• 목요일 밤에 = on Thursday night

You can sometimes hear 목요일에 밤에, but it sounds heavier and less natural in everyday speech. Korean usually avoids marking both parts when one 에 is enough.

A similar pattern:

• 내일 아침에 = tomorrow morning
• 금요일 저녁에 = Friday evening

So 목요일 밤에 is the normal, natural way to say it.

밤 means night, while 저녁 means evening.

So:

• 목요일 밤에 = on Thursday night
• 목요일 저녁에 = on Thursday evening

The difference is similar to English:

• 저녁: earlier, around dinnertime/evening
• 밤: later, nighttime

If the action happens fairly late, 밤에 makes sense. If it happens earlier, 저녁에 might sound more natural.

Yes, 병 can mean different things depending on context.

Common meanings include:

• 병 = bottle
• 병 = illness/disease

In this sentence, because it appears with 캔 and 분리수거하다, it clearly means bottle.

This is very normal in Korean: one word can have multiple meanings, and context tells you which one is intended.

이랑 means and or with, depending on context.

In this sentence, it connects two nouns:

• 병이랑 캔 = bottles and cans

It is a very common, natural spoken connector.

Other ways to say and between nouns are:

• 병과 캔 — a bit more formal/written
• 병하고 캔 — very common in speech
• 병 및 캔 — quite formal, often written

So 이랑 is perfectly natural in everyday conversation.

Because the whole phrase 병이랑 캔 works together as one object of the verb, Korean often puts the object marker only on the last noun:

• 병이랑 캔을 분리수거해요

This is the normal pattern.

Think of it like:

• [bottles and cans]
  • object marker

You would not normally say:

• 병을이랑 캔을 ✘

You may also see:

• 병과 캔을
• 병하고 캔을

Again, the object marker usually appears once at the end of the connected noun phrase.

The dictionary form is 분리수거하다.

It is made from:

• 분리 = separation
• 수거 = collection
• 하다 = to do

So literally it is something like to do separated collection, but in real Korean it means to sort and dispose of recyclables separately or to separate recycling.

The 해요 form is the present-tense polite form:

• 분리수거하다 → 분리수거해요

Not exactly.

English recycle often focuses on the general idea of recycling. Korean 분리수거하다 specifically emphasizes sorting items by type for proper disposal or recycling.

So it often means things like:

• separating bottles, cans, paper, plastic, etc.
• putting them in the correct recycling categories

In everyday Korean, this is a very common verb when talking about household trash and recycling rules.

Yes. 해요 is the polite, everyday style.

So 분리수거해요 is appropriate in many normal situations:

• conversation
• class examples
• polite everyday speech

Other styles:

• 분리수거합니다 — more formal
• 분리수거해 — casual, informal
• 분리수거해요 — polite and common

So this sentence is in a very useful standard polite style for learners.

Korean nouns usually do not change form for singular vs. plural the way English nouns do.

So:

• 병 can mean bottle or bottles
• 캔 can mean can or cans

The context tells you which meaning is intended. In a recycling sentence like this, it naturally sounds like bottles and cans in general, not just one of each.

Korean does have a plural marker 들, but it is not necessary here:

• 병이랑 캔을 sounds natural
• 병들이랑 캔들을 would sound unnecessary or unnatural in this context

Sometimes Korean drops 에 with time expressions, but here 에 sounds natural and standard.

Compare:

• 목요일 밤에 분리수거해요 — natural and clear
• 목요일 밤 분리수거해요 — possible in casual speech, but less standard

With words like 밤, 아침, 저녁, and specific times, 에 is very commonly used.

So for a learner, 목요일 밤에 is the safest and most natural choice.

The sentence follows normal Korean word order:

• 목요일 밤에 = time
• 병이랑 캔을 = object
• 분리수거해요 = verb

So the pattern is basically:

time + object + verb

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

So even if the English meaning is already clear, this sentence is a good example of standard Korean sentence structure.
