-면 is the conditional ending meaning if/when.

So 비가 오면 literally means if rain comes, which is the Korean way to say if it rains or when it rains.

In a sentence like this, both English translations can work depending on context:

• If it rains, shake off the umbrella and put it beside the entrance.
• When it rains, shake off the umbrella and put it beside the entrance.

Korean often does not sharply distinguish if and when here. The situation tells you which sounds more natural in English.

This is just the standard Korean expression for rain:

• 비가 오다 = to rain
• literally: rain comes

It is an idiomatic Korean pattern. Similarly, Korean also says:

• 눈이 오다 = to snow

So even though 오다 often means to come, in weather expressions it combines naturally with 비 and 눈.

In 비가 오다, 비 is the subject of the verb, so it takes the subject marker 가.

• 비가 오다 = rain falls / it rains

You will usually learn this whole expression as a set phrase. Native speakers do not normally say 비를 오다.

Yes. In this sentence, 털다 means to shake something off or to shake off water/dust from something.

So 우산을 털고 means:

• shake off the umbrella
• more naturally in English: shake the water off the umbrella

The object marker 을 is attached to 우산, because the umbrella is the thing being shaken.

This verb has other meanings in other contexts, so learners often get confused. For example, 털다 can also mean things like brush off, dust off, or even other unrelated meanings in different expressions. Here, the context clearly means shake off the rainwater.

Because Korean often leaves obvious information unstated.

In 우산을 털고, the thing being removed is not said directly, but everyone understands it is probably:

• rainwater
• moisture
• maybe dust, depending on context

Since the sentence already begins with 비가 오면, it is very clear that you are shaking off the rain from the umbrella. Korean often sounds more natural when it omits things that are easy to infer.

-고 links actions together. Here it means something like:

• shake off the umbrella and
• after shaking off the umbrella,

So the sentence gives two actions in sequence:

1. 우산을 털고 = shake off the umbrella
2. 현관 옆에 두세요 = put it beside the entrance

In this kind of instruction, -고 is very common for connecting steps.

현관 옆에 means beside the entrance or next to the entryway.

Breakdown:

• 현관 = entrance / entryway / foyer
• 옆 = side
• 에 = location marker, meaning at / in / on / to, depending on context

With verbs like 두다 meaning to place / leave, 에 marks the place where something is put.

So:

• 현관 옆에 두세요 = please put it beside the entrance

문 means door.

현관 means the entry area or entrance space, not just the physical door itself. In many homes, 현관 refers to the small area inside the entrance where people take off shoes or leave umbrellas.

So 현관 옆에 suggests a location near the entrance area, not necessarily literally attached to the door.

Yes, both can mean put/place, but there is a nuance.

• 놓다 = to put/place something somewhere
• 두다 = to put and leave it there

In this sentence, 두세요 is very natural because the umbrella is not just being placed for a moment; it is being left there.

So:

• 현관 옆에 두세요 = please leave it beside the entrance

If you used 놓으세요, it would still be understandable, but 두세요 often feels more natural for put it there and keep it there.

-세요 makes the sentence a polite request or polite instruction.

• 두다 = to put / leave
• 두세요 = please put / please leave

This form is commonly used for:

• polite instructions
• signs
• requests to guests
• everyday respectful speech

So the overall tone is polite and appropriate for speaking to someone you do not want to sound too blunt with.

It is best understood as a polite instruction or request.

Because of -세요, it is not harsh. Depending on context, it could be:

• something said to a guest
• a polite house rule
• a sign or notice

So in English, it might be translated as:

• Please shake off your umbrella and leave it beside the entrance.
• When it rains, please shake off the umbrella and place it by the entrance.

Korean often omits subjects when they are obvious from context.

In an instruction using -세요, the implied subject is usually you. So although Korean does not say it, the meaning is understood as:

• (You) shake off the umbrella and put it beside the entrance.

This is extremely normal in Korean.

Yes. A very literal breakdown is:

• 비가 오면 = if/when it rains
• 우산을 = the umbrella
• 털고 = shake off, and then
• 현관 옆에 = beside the entrance
• 두세요 = please leave it

So the sentence follows a very typical Korean pattern:

condition → object/action 1 → location/action 2 → final verb

The most important thing to remember is that Korean puts the main final verb at the end, so you often need to wait until the end of the sentence for the full structure to become clear.
