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

So 오늘은 is not just today; it has a nuance like:

• as for today
• today, at least
• today

In many cases, English does not translate this particle directly, but it helps set the frame for what follows.

Without it:

• 오늘 공원에서 오래 걷고 싶어요. = still natural, just a little more neutral/plain

With it:

• 오늘은 공원에서 오래 걷고 싶어요. = as for today, I want to walk for a long time in the park

It can sometimes give a slight contrastive feeling, as if today is being distinguished from other days.

This is a very common question because both 에 and 에서 can relate to places, but they do different jobs.

• 에 = to / at / in, often for destination or existence
• 에서 = at/in a place where an action happens

Here, 걷다 (to walk) is an action, and the walking happens in the park, so Korean uses 에서:

• 공원에서 걷어요. = I walk in the park.

If you used 공원에, it would usually sound like:

• motion to the park
• or a different structure, depending on the verb

Compare:

• 공원에 가고 싶어요. = I want to go to the park.
• 공원에서 걷고 싶어요. = I want to walk in the park.

오래 is an adverb meaning for a long time or long.

In this sentence, it modifies 걷고 싶어요, so it means the speaker wants to walk for a long time.

Examples:

• 오래 기다렸어요. = I waited for a long time.
• 오래 자고 싶어요. = I want to sleep for a long time.
• 오래 걷고 싶어요. = I want to walk for a long time.

A useful thing to remember: 오래 is not the adjective old in English. It refers to duration of time, not age.

In Korean, adverbs usually come before the verb they modify.

So:

• 공원에서 오래 걷고 싶어요. = natural

Here 오래 comes right before 걷고 싶어요, because it describes the walking.

In general:

• 천천히 걸어요. = walk slowly
• 많이 먹어요. = eat a lot
• 오래 공부하고 싶어요. = want to study for a long time

Korean word order is often flexible, but placing the adverb before the verb is the most standard and easiest pattern for learners.

This is the pattern:

• verb stem + 고 싶어요 = want to do

So here:

• 걷다 = to walk
• verb stem = 걷-
• 걷고 싶어요 = want to walk

This is one of the most useful Korean patterns for expressing wants.

More examples:

• 먹고 싶어요 = want to eat
• 가고 싶어요 = want to go
• 쉬고 싶어요 = want to rest

A small nuance: -고 싶어요 is normally used for the speaker's own desire.
For example:

• 저는 걷고 싶어요. = I want to walk.

If you want to talk about what someone else wants, Korean often uses different expressions, such as -고 싶어해요 in many contexts.

This is a great question because 걷다 changes in some forms but not others.

걷다 is one of those verbs where the ㄷ can change to ㄹ when followed by a vowel.

For example:

• 걷다 → dictionary form
• 걸어요 = walk / am walking
• 걸어서 = by walking / walking and

But in 걷고, the ending starts with ㄱ, which is a consonant, not a vowel. So the ㄷ stays the same:

• 걷고 싶어요 = correct
• 걸고 싶어요 = wrong here

So the rule is:

• before a vowel: 걷- often becomes 걸-
• before a consonant: it usually stays 걷-

Yes. -어요 makes it a polite, everyday style sentence, often called the 해요체 style.

So 오늘은 공원에서 오래 걷고 싶어요 is polite and natural in many normal situations.

Compare:

• 걷고 싶어요 = polite everyday
• 걷고 싶습니다 = more formal
• 걷고 싶어 = casual, used with close friends or younger people

So if you are speaking to someone you do not know well, 걷고 싶어요 is a very safe choice.

Yes. Korean often leaves out information that is clear from context.

There is no explicit subject here, but Korean does that all the time. The sentence naturally implies I in many situations:

• (저는) 오늘은 공원에서 오래 걷고 싶어요.

You can also omit 오늘은 if the time is already understood:

• 공원에서 오래 걷고 싶어요. = I want to walk in the park for a long time.

You could add a subject if needed:

• 저는 오늘은 공원에서 오래 걷고 싶어요.

But in normal Korean, leaving out obvious subjects is very natural.

Often, yes.

Because -은/는 can mark topic and also create a mild contrast, 오늘은 may suggest something like:

• today, at least
• as for today
• today rather than on some other day

Depending on context, it could imply things like:

• maybe yesterday I did not want to
• maybe tomorrow I have other plans
• but today, I want to walk for a long time in the park

This contrast is often subtle and may not need to be translated into English, but it is useful to feel it.

You can negate 싶어요:

• 오늘은 공원에서 오래 걷고 싶지 않아요.

This means:

• I don't want to walk for a long time in the park today.

Breakdown:

• 걷고 싶어요 = want to walk
• 걷고 싶지 않아요 = do not want to walk

This is a very common pattern:

• 먹고 싶어요 → 먹고 싶지 않아요
• 가고 싶어요 → 가고 싶지 않아요

So once you learn -고 싶어요, the negative form is easy to build.
