는 is the topic particle. In 오늘은, it marks today as the topic of the sentence.

So 오늘은 means something like:

• as for today
• today
• speaking of today

It can also give a slight contrastive feeling, like today (at least) or today in particular. In this sentence, it helps set the scene: Today, since it’s cold, I wear gloves.

추워서 comes from the adjective 춥다 meaning to be cold.

It changes like this:

• 춥다 → stem 춥-
• irregular change: ㅂ changes to 우
• 추우-
• plus -어서 → 추워서

So 추워서 means:

• because it’s cold
• since it’s cold

The -아서/어서 form is very commonly used to connect two clauses and show reason or cause.

Both can mean because it’s cold, I wear gloves, but they feel slightly different.

• 추워서: a more neutral, natural connection of cause and result
• 추우니까: often feels a bit more explanatory, emphatic, or like giving a reason

So:

• 오늘은 추워서 장갑을 껴요. = Today it’s cold, so I wear gloves.
• 오늘은 추우니까 장갑을 껴요. = Today it’s cold, so I’m wearing gloves / because it’s cold, you see

Both are correct, but -아서/어서 is very common in everyday cause-and-effect statements like this.

을 is the object particle. It marks 장갑 (gloves) as the thing being worn.

• 장갑 = gloves
• 장갑을 = gloves + object marker

In Korean, the thing you wear is often treated as the object of the verb:

• 장갑을 껴요 = wear/put on gloves

Since 장갑 ends in a consonant, it takes 을. If a noun ends in a vowel, it takes 를.

Korean uses different verbs for different kinds of things you wear.

• 입다 = wear clothes
• 신다 = wear shoes
• 쓰다 = wear a hat / glasses
• 끼다 = wear things on your hands, fingers, or sometimes face openings such as rings or gloves

So:

• 장갑을 껴요 = wear gloves
• 반지를 껴요 = wear a ring

You would not normally say 장갑을 입어요, because 입다 is for clothing like shirts, coats, and pants.

It can mean either, depending on context.

끼다 can describe:

• putting on gloves
• wearing gloves

In this sentence, 오늘은 추워서 장갑을 껴요, English could naturally be:

• It’s cold today, so I wear gloves.
• It’s cold today, so I put on gloves.
• Since it’s cold today, I’m wearing gloves.

Korean present tense often covers both habitual and immediate present meanings, so context decides the best English translation.

Korean often omits the subject when it is clear from context.

So 오늘은 추워서 장갑을 껴요 could mean:

• I wear gloves because it’s cold today
• I’m putting on gloves because it’s cold today
• sometimes even we or someone wears gloves, depending on the situation

In most everyday situations, listeners naturally understand the subject from context. Korean does this much more often than English.

껴요 is in the polite present style, often called the 해요체 form.

This is one of the most common polite endings in Korean conversation. It is appropriate in many everyday situations, such as speaking to:

• someone you do not know well
• a classmate in a polite setting
• a teacher
• a customer
• an older person, depending on the relationship

The plain dictionary form would be 끼다.
The polite form is 껴요.

The base word 춥다 is usually called a descriptive verb in Korean grammar, though English learners often think of it as an adjective because it means to be cold.

In the sentence:

• 추워서 = connected form of 춥다
• it describes the condition being cold
• then it connects to the next action: wearing gloves

So even though it feels like an adjective in English, in Korean it behaves like a predicate that can be conjugated.

껴요 is pronounced roughly like kkyeo-yo.

A few pronunciation notes:

• ㄲ is a tense k/gg sound, stronger than plain ㄱ
• 껴 sounds like kkyeo
• then 요 is yo

So the whole word is approximately:

• kkyeo-yo

For many learners, the hardest part is the tense consonant ㄲ and the 껴 combination.

Yes, in casual speech, Korean often drops particles when the meaning is still clear.

So all of these may be heard:

• 오늘은 추워서 장갑을 껴요.
• 오늘 추워서 장갑을 껴요.
• 오늘은 추워서 장갑 껴요.
• 오늘 추워서 장갑 껴요.

However, for learners, the fully marked version is very useful because it clearly shows the grammar:

• 오늘은 = topic
• 장갑을 = object

So the original sentence is a good textbook-style version.

Not exactly. 추워서 here most naturally means because it is cold or because the weather is cold.

Korean often leaves the subject unstated, so the sentence does not explicitly say whether:

• the weather is cold
• I am cold

But in this context, with 장갑을 껴요, most people understand it as:

• It’s cold today, so I wear gloves

If you specifically wanted to say I feel cold, Korean might use a sentence like:

• 오늘은 제가 추워서 장갑을 껴요.

Even then, context matters, but the original sentence most naturally refers to the cold weather.

The structure is:

• 오늘은 = as for today
• 추워서 = because it’s cold
• 장갑을 = gloves (object)
• 껴요 = wear / put on

So the pattern is:

Topic + reason + object + verb

This is very common in Korean. The verb comes at the end, and the reason clause comes before the main action.
