주말에 means on the weekend or at the weekend.

The particle 에 is often used with time expressions to mean at/on/in:

• 아침에 = in the morning
• 월요일에 = on Monday
• 주말에 = on the weekend

In this sentence, 주말에 sets the time for the action.

에서 is used because the park is the place where the action happens.

• 공원에서 조깅하다 = to jog in the park
• 에서 marks the location of an action

By contrast, 에 is often used for:

1. destination
   • 공원에 가요 = I go to the park
2. time
   • 주말에 = on the weekend
3. location with 있다/없다
   • 공원에 사람이 많아요 = There are many people in the park

So:

• 공원에서 조깅해요 = jog in the park
• 공원에 가요 = go to the park

조깅할 때 means when (I) jog or when jogging.

It is made from:

• 조깅하다 = to jog
• 할 = the modifier form of 하다
• 때 = time / when

So literally, it is something like:

• the time when one jogs

In natural English, that becomes:

• when jogging
• when I jog

This is a very common learner question.

With 때, Korean usually uses:

• verb stem + -(으)ㄹ 때 for general or future-like situations
• verb stem + -았/었을 때 for past situations

So:

• 조깅할 때 = when jogging / when I jog
• 조깅했을 때 = when I jogged / when I was jogging in the past

While 하는 can modify nouns in other situations, with 때, -(으)ㄹ 때 is the normal pattern for a general repeated action like this sentence.

So 조깅할 때 운동화를 신어요 means:

• I wear sneakers when I jog
• not specifically one past event, but a habitual situation

를 marks the direct object of the verb.

Here:

• 운동화 = sneakers / athletic shoes
• 운동화를 = sneakers + object marker

The verb is 신어요 (to wear footwear), so the thing being worn is the object:

• 운동화를 신어요 = wear sneakers

This is similar to:

• 모자를 써요 = wear a hat
• 옷을 입어요 = wear clothes
• 안경을 써요 = wear glasses

Korean uses different verbs for wearing depending on the item.

• 입어요 = wear clothes
• 신어요 = wear shoes, socks, footwear
• 써요 = wear a hat, glasses, mask
• 끼어요 = wear rings, gloves, etc. depending on context
• 메어요 or 매요 = wear/carry a bag, tie a necktie, etc. depending on the item

So:

• 운동화를 신어요 = wear sneakers
• 티셔츠를 입어요 = wear a T-shirt

English uses wear for all of these, but Korean splits them up by category.

It usually sounds habitual here.

주말에 공원에서 조깅할 때 운동화를 신어요 most naturally means:

• On weekends, when I jog in the park, I wear sneakers.
• I wear sneakers when I jog in the park on weekends.

The present tense -어요 in Korean is often used for habits and general facts, not only for actions happening right now.

If you wanted to emphasize one specific weekend, you would usually need more context:

• 이번 주말에 = this weekend
• 지난 주말에 = last weekend

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

So even though English usually needs I, Korean often just says:

• 운동화를 신어요 = I wear sneakers, we wear sneakers, or even they wear sneakers, depending on context

In this sentence, the omitted subject is most naturally:

• I

So the full idea is something like:

• 저는 주말에 공원에서 조깅할 때 운동화를 신어요.

But saying 저는 is often unnecessary.

신어요 is in the present informal polite style, often called the -어요 form.

This form is very common in everyday polite conversation.

From the dictionary form:

• 신다 = to wear footwear

It becomes:

• 신어요 = wear / am wearing

In this sentence, it expresses a habitual present:

• I wear sneakers

If you wanted a more casual form:

• 신어

If you wanted a more formal style:

• 신습니다

Yes. Korean word order is flexible as long as the particles and verb forms make the relationships clear.

Original:

• 주말에 공원에서 조깅할 때 운동화를 신어요.

You could also say:

• 공원에서 주말에 조깅할 때 운동화를 신어요.
• 운동화는 주말에 공원에서 조깅할 때 신어요.
  (with extra emphasis on the sneakers)

That said, the original order sounds natural and straightforward:

1. time
2. place
3. when clause
4. object
5. verb

And the verb usually stays at the end.

Yes, 조깅하다 is a normal and understandable word in Korean. It is a loanword-based verb:

• 조깅 = jogging
• 하다 = to do

So 조깅하다 literally means to do jogging, but naturally it means to jog.

Depending on context, Koreans might also use other expressions like:

• 달리기하다 = to do running
• 뛰다 = to run

But 공원에서 조깅할 때 sounds natural.

Yes. 운동화 literally refers to athletic shoes or sports shoes, and in many everyday contexts it is naturally translated as:

• sneakers
• trainers

So in this sentence, sneakers is a very natural translation, but depending on context it could also mean running shoes or athletic shoes more generally.

Yes, absolutely. This sentence is natural and clear.

주말에 공원에서 조깅할 때 운동화를 신어요 expresses that idea well.

A few natural English translations are:

• I wear sneakers when I jog in the park on weekends.
• On weekends, when I go jogging in the park, I wear sneakers.
• When I jog in the park on weekends, I wear sneakers.

All of those match the Korean sentence well.
