Learn Hardcore Korean: jumalmada chingudeulgwa gongwoneseo moyeoyo. - Every weekend, I gather with friends at the park.

It means “every/each.” It attaches to a noun to express regular repetition. Examples: 날마다 (every day), 사람마다 (each person). So 주말마다 = every weekend.

Do I need to add -에 after 주말마다? Why not “주말마다에”?

No. -마다 already makes the noun a time/frequency expression, so 주말마다 is complete. 주말마다에 is ungrammatical. For a looser “on weekends (generally),” you can use 주말에는 (topic-marked).

Can I say 매주 instead of 주말마다?

매주 = every week (broad). 주말마다 = every weekend (specific). If it only happens on weekends, use 주말마다. You can also say 매 주말(에), which is natural.

Is 매주말 correct?

Prefer 매 주말(에) or 주말마다. The single-word form 매주말 isn’t standard; people may say it, but standard writing favors the spaced 매 주말.

Who is the subject here? Why is it omitted?

Korean often omits obvious subjects. The implied subject is “we.” You can say 우리는/저희는 주말마다 친구들과 공원에서 모여요, but it’s typically dropped when clear from context.

What does 친구들과 mean, and how is it different from 친구하고 or 친구랑?

All mean “with friends”:

친구들과: more formal/written (uses -과/와).
친구하고: neutral, common in speech.
친구랑/친구들이랑: casual. Choose based on formality.

Do I have to use 들 in 친구들? Can I just say 친구와/친구하고?

-들 marks plurality but is often optional. With “with,” speakers often add -들 to stress a group, but 친구와/친구하고 is also natural if plurality is understood.

Why is it 과 and not 와 here?

Use -과 after a final consonant and -와 after a vowel. The base here is 친구들 (ends with the consonant ㄹ), so 친구들과 is correct. With 친구 (no final consonant), it would be 친구와.

What does -에서 mean in 공원에서? How is it different from -에?

-에서 marks the location where an action happens (“at/in” as an activity site). -에 marks location of existence or destination (“at/to”). Compare:

공원에서 모여요 = we gather in/at the park (action occurs there).
공원에 있어요 = we are at the park (existence).

Can I say 공원에 모여요 instead of 공원에서 모여요?

With 모이다 (“to gather”), both 장소에 모이다 and 장소에서 모이다 are used. -에 slightly emphasizes the destination (“gather at”), while -에서 highlights the action happening there. Both sound natural.

Why is it 모여요 and not 모아요? How do you conjugate 모이다?

The stem is 모이-. When adding -어요, 이 + 어 contracts to 여: 모이어요 → 모여요. Past: 모였어요. Future: 모일 거예요. (Same contraction pattern: 보이다 → 보여요.)

What’s the difference between 모여요 and 만나요?

모이다: intransitive “to gather/assemble.” Takes a “with” phrase: 친구들과 모여요.
만나다: transitive “to meet (someone).” Takes an object: 친구들을 만나요. 모이다 tends to imply a group coming together; 만나다 can be one-on-one or group.

Do I need 같이 or 함께 to say “together”?

Optional. 모이다 already implies togetherness. 친구들과 같이/함께 공원에서 모여요 is natural but a bit redundant; it adds emphasis.

Is the word order fixed? Can I move parts around?

Flexible as long as the verb is last. Natural variants:

주말마다 친구들과 공원에서 모여요 (time–with whom–place–verb).
주말마다 공원에서 친구들과 모여요 (time–place–with whom–verb).
친구들과 주말마다 공원에서 모여요. All are fine.

What politeness level is 모여요? How else can I say it?

-어요/-아요 is polite informal. Other options:

Casual: 모여.
Formal/polite (announcements): 모입니다.
Honorific request: 모이세요.
Past/future: 모였어요 / 모일 거예요.
