In this sentence, it actually is there: 마대를.

• 마대 = sack
• 를 = object marker

So 마대를 means the sack as the direct object of the verb 움직이다/움직이다 in causative-like use here = to move.

혼자 means alone or by oneself.

So 마대를 혼자 움직이지 마십시오 means something like:

• Do not move the sack by yourself
• Do not move the sack alone

It tells the listener that this is not something one person should do without help.

In Korean, adverbs like 혼자 often come before the verb phrase they modify.

So:

• 마대를 = the sack
• 혼자 = alone
• 움직이지 마십시오 = do not move

That word order is very natural in Korean. English might say Don’t move the sack alone, but Korean commonly puts the adverb before the verb.

This is a formal negative command.

It is made from:

• 움직이다 = to move
• -지 마십시오 = please do not / do not

So:

• 움직이지 마십시오 = Do not move it / Please do not move it

This form is very common in:

• signs
• instructions
• announcements
• workplace safety notices
• polite formal speech

-지 마십시오 is attached to a verb stem to tell someone not to do something in a very formal and polite way.

Pattern:

• verb stem + 지 마십시오

Examples:

• 들어가지 마십시오 = Do not enter.
• 만지지 마십시오 = Do not touch.
• 사진을 찍지 마십시오 = Do not take photos.
• 움직이지 마십시오 = Do not move.

So here, 움직이다 becomes 움직이지 마십시오.

Good question. 움직이다 can be used both ways depending on context.

1. Intransitive: something moves

   • 차가 움직인다 = The car moves.

2. Transitive: to move something

   • 짐을 움직이다 = to move luggage
   • 마대를 움직이다 = to move the sack

So in this sentence, it is being used transitively: someone is moving the sack.

Both are negative commands, but the level of formality is different.

• -지 마세요 = polite, everyday spoken style
• -지 마십시오 = more formal, official, stiff, common on signs and notices

Compare:

• 혼자 움직이지 마세요 = Don’t move it alone.
  → natural in conversation
• 혼자 움직이지 마십시오 = Do not move it alone.
  → formal notice or instruction

Because this sounds like a warning or posted instruction, 마십시오 fits well.

Yes, very strongly.

A sentence like 마대를 혼자 움직이지 마십시오 would often appear in a workplace, warehouse, construction site, or industrial setting. It suggests:

• the sack is heavy
• it may be dangerous
• more than one person may be needed
• the listener should ask for help or use equipment

So even though the literal meaning is simply Do not move the sack by yourself, the practical meaning is often For safety, do not attempt to move this alone.

Yes. In many contexts, 혼자 covers both ideas.

Depending on the translation, it can sound like:

• alone
• by yourself
• on your own

In this sentence, by yourself is probably the most natural English choice, because the warning is about performing an action without assistance.

Yes, and it might even sound more natural in some contexts.

• 움직이다 = to move
• 옮기다 = to move/carry/transfer something from one place to another

So:

• 마대를 혼자 움직이지 마십시오 = Do not move the sack by yourself.
• 마대를 혼자 옮기지 마십시오 = Do not carry/move the sack by yourself.

If the meaning is specifically about lifting or transporting the sack, 옮기다 may sound a bit more specific. But 움직이다 is still understandable and natural enough, especially in general warnings.

Grammatically, Korean commands are directed at the listener, but on signs they are usually understood as instructions to anyone reading them.

So even though the form is singular in effect, in practice it means:

• No one should move this sack alone
• People should not move this sack by themselves

That is very common for Korean warning signs and notices.
