주말에 means on the weekend or at the weekend.

The particle 에 is often used with time expressions to mark when something happens. So:

• 주말 = weekend
• 주말에 = on the weekend

In this sentence, it tells you when the action of playing happens.

친구들과 means with friends.

Breakdown:

• 친구 = friend
• 들 = plural marker, so 친구들 = friends
• 과 = with (more formal/written style)
• 친구들과 = with friends

The 과 changes to 과/와 depending on the previous sound, but here it appears as 들과 because it is attached after 친구들.

You could also hear:

• 친구들하고
• 친구들이랑

These also mean with friends, but they feel a bit more conversational.

Often, yes—Korean can leave out plural marking when the meaning is clear from context.

So both of these can work:

• 친구들과 = with friends
• 친구와 = with a friend / with friends, depending on context

However, 친구들과 clearly emphasizes more than one friend, so it is natural here if the speaker really means friends.

Because 에서 marks the place where an action happens.

Here, the action is 놀아요 = play / hang out, so:

• 공원에서 놀아요 = play in the park

Compare:

• 에 = location/destination/time
• 에서 = place where an action occurs

Examples:

• 공원에 가요 = I go to the park
• 공원에서 놀아요 = I play at the park

So in this sentence, 에서 is the correct particle because the park is the location of the activity.

재미있게 means something like in a fun way, enjoyably, or simply for fun.

It comes from the adjective:

• 재미있다 = to be fun / interesting

To turn an adjective into an adverb in Korean, you often use -게:

• 재미있다 → 재미있게

So:

• 재미있게 놀아요 = play enjoyably / have fun playing

This is similar to how English changes happy to happily, though the Korean grammar works a bit differently.

The dictionary form is 놀다, which means to play, to hang out, or sometimes to spend time having fun.

In polite present-style speech, 놀다 becomes 놀아요.

So:

• 놀다 = dictionary form
• 놀아요 = polite everyday form

This is the style Korean learners often learn early because it is polite and very common in conversation.

It can mean both, depending on context.

In this sentence, 주말에 친구들과 공원에서 재미있게 놀아요 often sounds like a habitual action:

• I play/hang out with friends in the park on weekends
• On weekends, I have fun with friends at the park

Korean present tense often covers:

• simple present
• habitual actions
• sometimes near future

So context decides the most natural English translation.

Korean word order is more flexible than English, as long as the particles are clear.

Original:

• 주말에 친구들과 공원에서 재미있게 놀아요.

Possible rearrangements:

• 친구들과 주말에 공원에서 재미있게 놀아요.
• 공원에서 주말에 친구들과 재미있게 놀아요.

These are all understandable, though the original sounds very natural.

The basic rule is that the verb usually comes at the end, while time, place, and companions can move around for emphasis.

Yes, you can think of it that way.

• 친구들과 = with friends
• 공원에서 = in/at the park

Together, they describe who you are with and where the action happens.

So the sentence builds up like this:

• 주말에 = on weekends
• 친구들과 = with friends
• 공원에서 = at the park
• 재미있게 = enjoyably / for fun
• 놀아요 = play / hang out

Korean often stacks these pieces before the final verb.

Adults can absolutely use it too.

놀다 does not only mean to play like a child. It can also mean:

• to hang out
• to have fun
• to spend leisure time

So in this sentence, depending on context, it could mean:

• children playing in the park
• friends hanging out in the park
• people spending enjoyable time together

That is why English translations may vary.

놀아요 by itself just means play / hang out.

Adding 재미있게 gives extra detail:

• 놀아요 = play / hang out
• 재미있게 놀아요 = have fun playing / play enjoyably / have a good time

So 재미있게 makes the sentence sound more vivid and positive.

A few parts may sound a little different from how they look in writing:

• 재미있게 is often pronounced close to 재미읻께
• 놀아요 is often pronounced close to 노라요

So the whole sentence may sound roughly like:

• 주말에 친구들과 공원에서 재미읻께 노라요

You should still write it as 재미있게 놀아요, but it is helpful to know the spoken pronunciation.

Yes, but the meaning changes slightly.

• 주말에 = on the weekend / on weekends
• 주말마다 = every weekend

So:

• 주말에 친구들과 공원에서 재미있게 놀아요.
  = On weekends, I play/hang out with friends in the park.

• 주말마다 친구들과 공원에서 재미있게 놀아요.
  = Every weekend, I play/hang out with friends in the park.

주말마다 sounds a bit more explicitly repetitive.
