주말마다 means every weekend.

The particle -마다 attaches to a noun and means every, each, or whenever that time/unit comes around.

Examples:

• 주말마다 = every weekend
• 월요일마다 = every Monday
• 해마다 = every year

So 주말마다 복지관에서... means At the welfare center every weekend...

Yes, but the difference is small.

• 주말마다 = every weekend
• 매주 = every week
• 매주말 = every weekend

In this sentence, 주말마다 sounds very natural because the action happens specifically on weekends.

A subtle difference:

• 매주 focuses on each week
• 주말마다 / 매주말 focuses on the weekend time within each week

So if the speaker really means the action happens on weekends, 주말마다 is a very good choice.

Because 에서 marks the place where an action happens.

• 복지관에서 모금해요 = We raise funds at the welfare center
• 복지관에 usually marks destination or location of existence

Compare:

• 복지관에 가요 = I go to the welfare center
• 복지관에 있어요 = I am at the welfare center
• 복지관에서 일해요 = I work at the welfare center

Since 모금하다 is an action being performed there, 에서 is correct.

복지관 usually means a welfare center or community welfare center.

It is a place that provides social services, support programs, classes, activities, or assistance for local residents, seniors, people with disabilities, and others depending on the type of center.

So in this sentence, 복지관에서 suggests the fundraising is being done through or at a welfare center.

지역사회 means the local community or the community in a social/civic sense.

• 지역 = region / local area
• 사회 = society / community

Together, 지역사회 means local community.

-를/을 위해 means for, for the sake of, or for the benefit of.

So:

• 지역사회를 위해 = for the local community / for the benefit of the local community

In the sentence, it tells you the purpose of the fundraising.

Good question. In N을/를 위해(서), the noun still takes the object particle 을/를.

So the pattern is:

• 사람들을 위해 = for people
• 회사를 위해 = for the company
• 지역사회를 위해 = for the local community

You can think of 위해 as part of a grammatical expression meaning for the sake of.

So 지역사회 + 를 + 위해 is the normal structure.

In this sentence, the difference is very small.

• 지역사회를 위해 모금해요
• 지역사회를 위해서 모금해요

Both mean essentially the same thing: raise funds for the local community.

In many everyday contexts:

• 위해 sounds a bit shorter and lighter
• 위해서 can sound slightly more explicit or emphasized

But both are natural, and either one works here.

모금해요 comes from 모금하다, which means to raise funds, to collect donations, or to fundraise.

So:

• 모금해요 = raise funds / fundraise

This verb is commonly used in charity, nonprofit, school, or community contexts.

Examples:

• 성금을 모금해요 = raise donation money
• 기부금을 모금해요 = collect donations

In your sentence, the object is omitted because it is easy to understand from context. The meaning is simply We fundraise.

Because 모금하다 is a 하다 verb.

Breakdown:

• 모금 = fundraising / fund collection
• 하다 = to do

So:

• dictionary form: 모금하다
• polite present form: 모금해요

This happens because 하다 becomes 해요 in the polite present tense.

Other examples:

• 공부하다 → 공부해요
• 운동하다 → 운동해요
• 준비하다 → 준비해요

Korean often leaves out the subject when it is already understood from context.

So 주말마다 복지관에서 지역사회를 위해 모금해요 could mean:

• I raise funds...
• We raise funds...
• They raise funds...

The actual subject depends on the situation.

This is very normal in Korean. If the subject is clear, Koreans usually do not repeat it.

If you wanted to include it, you could say:

• 저는 주말마다 복지관에서 지역사회를 위해 모금해요.
• 우리는 주말마다 복지관에서 지역사회를 위해 모금해요.

The sentence follows a very typical Korean pattern:

주말마다
every weekend

복지관에서
at the welfare center

지역사회를 위해
for the local community

모금해요
raise funds / fundraise

So the structure is roughly:

Time + Place + Purpose + Verb

Korean usually puts the main verb at the end, and information like time, place, and purpose comes before it.

Yes, depending on context, it can suggest either one.

Most directly, 복지관에서 means at the welfare center, the location where the fundraising happens.

But in real usage, it can also imply something like:

• fundraising as part of activities at the welfare center
• fundraising through the welfare center

Korean often leaves that kind of nuance to context. The sentence itself mainly tells you the action is connected to the welfare center as the place or setting.

You can include one, but it is not necessary.

Examples:

• 주말마다 복지관에서 지역사회를 위해 기부금을 모금해요.
• 주말마다 복지관에서 지역사회를 위해 성금을 모금해요.

These are more specific:

• 기부금 = donation money
• 성금 = relief/contribution money, often for charity

But in many cases, just 모금해요 is perfectly natural because the idea of collecting money or donations is already built into the verb.

모금해요 is in the informal polite style, often called the -요 form.

It is polite and very common in everyday conversation.

Levels:

• 모금해요 = polite, everyday
• 모금합니다 = more formal
• 모금해 = casual/intimate

So this sentence sounds natural in normal polite speech, like in conversation, class examples, or general description.

Usually 주말마다 means every weekend, not necessarily emphasizing both Saturday and Sunday individually.

It means that whenever the weekend comes around, the fundraising happens as a regular activity.

If you wanted to be more specific, you could say:

• 토요일마다 = every Saturday
• 일요일마다 = every Sunday
• 주말에 = on weekends
• 주말마다 = every weekend, regularly

So 주말마다 suggests a repeated weekend habit or routine.
