마대 refers to a large sack or bag, often a coarse bag used for things like trash, soil, grain, or construction materials.

So in this sentence, it is probably talking about a sack/bag that someone might leave somewhere.

가 is the subject particle, so 마대가 means the sack/bag as the thing being described.

Here, the first part of the sentence is:

마대가 무겁더라도
= even if the sack is heavy

So 마대 is the subject of 무겁다 (to be heavy), not the direct object of the whole sentence.

If it were 마대를, that would mark it as the object, which would not fit this structure as naturally in this sentence.

무겁더라도 means even if it is heavy or although it is heavy.

It comes from:

• 무겁다 = to be heavy
• -더라도 = even if / even though

So:

• 무겁더라도 = even if it is heavy

This grammar is often used when the speaker wants to say that the following instruction still applies regardless of that condition.

So the sentence is saying:

• Even if the sack is heavy, still do not put it beside the walking path.

Both can mean even if / even though, but -더라도 often sounds a bit more emphatic or more formal. It can carry the nuance of:

• regardless of that fact
• even granting that point

Compare:

• 무거워도 두지 마세요 = Even if it’s heavy, don’t place it there.
• 무겁더라도 두지 마십시오 = Even if it is heavy, do not place it there.

In signs, instructions, and formal warnings, -더라도 fits very naturally.

Because -더라도 attaches to the dictionary stem of the adjective here.

• 무겁다 → stem: 무겁-
• 무겁- + 더라도 → 무겁더라도

The form 무거워- appears with endings that begin with a vowel, such as:

• 무거워요
• 무거워서

But -더라도 begins with a consonant, so you use 무겁-.

산책로 = walking path, trail, promenade
옆 = side, next to
-에 = location marker

So 산책로 옆에 means:

• beside the walking path
• next to the trail
• at the side of the walkway

The particle 에 is used because this is the location where something is being placed.

Because 두다 means to put / place / leave, and the place where something is put is marked with 에.

So:

• 책상 위에 두다 = put it on the desk
• 문 앞에 두다 = put it in front of the door
• 산책로 옆에 두다 = put it beside the walking path

Here, 에 marks the destination/location of placement.

두지 마십시오 means please do not place it or do not leave it.

It is made from:

• 두다 = to put, place, leave
• -지 마십시오 = please do not ...

So:

• 두지 마십시오 = please do not put/leave (it)

This is a very formal and polite negative command, often seen in:

• signs
• public notices
• official instructions
• announcements

Both 두다 and 놓다 can mean to put/place, and in many situations they overlap.

But 두다 often has the nuance of:

• putting something somewhere and leaving it there
• placing something in a certain location as a state

That fits this sentence well, because the concern is not just the act of setting it down, but leaving the sack beside the walking path.

So 두지 마십시오 feels very natural for a warning like this.

The object is omitted because it is already understood from context.

The sentence mentions 마대 first, so the unstated meaning is essentially:

• 마대를 산책로 옆에 두지 마십시오
• Do not place/leave the sack beside the walking path

Korean often leaves out words that are obvious from context, especially pronouns and repeated nouns.

So the sentence literally feels more like:

• Even if the sack is heavy, beside the walking path, do not leave [it].

Because Korean commonly avoids repeating a noun when it is already clear.

The structure is:

• 마대가 무겁더라도 = even if the sack is heavy
• 산책로 옆에 두지 마십시오 = do not place/leave it beside the walking path

Even though English often repeats or implies it, Korean can simply omit the object entirely if the listener already knows what is being talked about.

This makes the sentence sound natural, not incomplete.

마십시오 is very formal and polite.

It is commonly used in:

• public signs
• official notices
• workplace instructions
• announcements to the general public

Compared with other forms:

• 두지 마 = don’t put it (casual)
• 두지 마세요 = please don’t put it (polite everyday)
• 두지 마십시오 = please do not place it (formal, official)

So this sentence sounds like a notice or rule, not casual conversation.

It sounds most like a formal instruction or rule.

Because of -더라도 plus 마십시오, the tone is:

• Even if you have that reason/excuse, the instruction still stands.

So the nuance is something like:

• Even if the sack is heavy, do not leave it beside the trail.

This sounds stronger than a mere suggestion.

Yes, depending on context, 무겁다 can imply more than just physical weight. It can suggest:

• it is heavy
• it is burdensome to carry
• it is inconvenient because of its weight

So the sentence may imply:

• Even if it is heavy and hard to move, do not leave it by the path.

That is often how this kind of warning works in real life: it blocks a possible excuse.

The sentence breaks down like this:

• 마대가 = the sack
• 무겁더라도 = even if it is heavy
• 산책로 옆에 = beside the walking path
• 두지 마십시오 = do not place/leave it

So the structure is:

[Even if X is the case] + [do not do Y]

More generally:

• A-더라도 B
• Even if A, B

In this sentence:

• Even if the sack is heavy, do not leave it beside the walking path.

Yes, it is a normal word, especially in signs, parks, apartment complexes, and public spaces.

It is made of:

• 산책 = walk, stroll
• 로 = road/path

So 산책로 means a path intended for walking or strolling.

Depending on context, English translations could include:

• walking path
• trail
• walkway
• promenade

A more casual or everyday polite version would be:

마대가 무거워도 산책로 옆에 두지 마세요.

Differences:

• 무겁더라도 → 무거워도
  both mean even if it’s heavy
• 두지 마십시오 → 두지 마세요
  both mean please don’t place it, but 마십시오 is more formal

So the original sentence sounds better for an official notice, while this version sounds more like spoken polite Korean.
