이/가 marks the subject of the verb. In 물이 끓으면, 물 is the thing doing the action 끓다 (to boil), so 물 takes 이.

• 물 = water
• 물이 = the water / water as the subject
• 끓다 = to boil

So 물이 끓으면 literally means if/when the water boils.

-으면 means if or when, depending on context.

In this sentence, 끓으면 comes from:

• 끓다 = to boil
• 끓으면 = if/when it boils

So 물이 끓으면 라면을 넣어요 means something like:

• When the water boils, add the ramen
• If the water boils, put in the ramen

In cooking instructions, when is often the most natural translation.

The -으면 part is a connective ending, not the final ending of the whole sentence. It links the first clause to the second clause.

The structure is:

• 물이 끓으면 = when the water boils
• 라면을 넣어요 = put in the ramen

Only the final verb of the sentence, 넣어요, carries the polite sentence ending -어요.

So Korean often works like this:

• first clause: connective form
• final clause: sentence-ending form

을/를 marks the direct object, the thing being acted on.

Here:

• 라면 = ramen
• 라면을 = ramen as the object
• 넣어요 = put in / add

So 라면을 넣어요 means add the ramen.

넣어요 is the polite present-style form of 넣다, which means to put in, to insert, or to add.

In cooking, it often means:

• put in
• add

So 라면을 넣어요 means add the ramen or put in the ramen.

Even though it looks like a present tense form, Korean present-style endings are also commonly used for:

• habitual actions
• instructions
• recipes
• step-by-step explanations

Korean often uses the present-style form for general instructions or sequences, especially in recipes, manuals, and explanations.

So 넣어요 does not necessarily mean I am adding it now. In this context, it means:

• then add the ramen
• you add the ramen
• one adds the ramen

This is very common in instructional Korean.

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

In a recipe or instruction, the understood subject is usually:

• you
• or a general one

So 라면을 넣어요 really means something like:

• you add the ramen
• then add the ramen

There is no need to say 당신은 because that would usually sound unnatural here.

Korean normally puts time, condition, or background information before the main action.

So the order is:

1. 물이 끓으면 = when the water boils
2. 라면을 넣어요 = add the ramen

This is very natural in Korean. English can also do this:

• When the water boils, add the ramen.

So the Korean word order is not unusual once you think of it that way.

Yes, grammatically -으면 can mean if. But in this context, when is usually the better translation.

That is because this sounds like a cooking instruction, where the boiling of the water is an expected step, not a doubtful possibility.

So:

• grammatical meaning: if/when
• most natural meaning here: when

Here 끓다 is intransitive, meaning to boil.

So:

• 물이 끓다 = the water boils

There is also 끓이다, which is transitive and means to boil something or to make something boil.

Compare:

• 물이 끓어요 = the water boils
• 물을 끓여요 = boil the water / make the water boil

That distinction is very useful in Korean.

Yes, you could, but the nuance is a little different.

• 물이 끓으면 = when/once the water boils
• 물이 끓을 때 = when the water is boiling / at the time the water boils

In cooking instructions, 끓으면 often sounds better for once it reaches a boil, add the ramen.

So 끓으면 emphasizes the condition or trigger for the next action.

A natural pronunciation is close to 끄르면 or 끌르면, depending on how carefully someone speaks. The exact sound changes can be tricky for learners.

The important part is that 끓 is not pronounced exactly the way it looks letter by letter. Korean often changes sounds in natural speech.

A learner-friendly breakdown is:

• 끓다 is commonly pronounced roughly like 끌타
• 끓으면 is commonly pronounced roughly like 끄르면

You do not need to master every sound rule immediately, but it is good to know that the written and spoken forms are slightly different here.
