Questions & Answers about yeogwonhago tapseunggwoneul gabang ane neoheo duseyo.

What does 하고 mean here? Is it just and?

Yes. In 여권하고 탑승권을, 하고 connects the two nouns and means and:

• 여권 = passport
• 탑승권 = boarding pass
• 여권하고 탑승권 = passport and boarding pass

In everyday speech, 하고 is a very common, natural way to join nouns. Other possibilities are:

• 여권과 탑승권
• 여권이랑 탑승권

They all mean basically the same thing here, though the level of formality differs a bit.

Why is there only one 을? Shouldn’t both nouns get an object marker?

In Korean, when two nouns are connected, it is very common for only the last noun to carry the case particle, and that particle applies to the whole phrase.

So:

• 여권하고 탑승권을
  means
• the passport and boarding pass as the object of the verb

You do not need to say 여권을 하고 탑승권을. In fact, that would sound wrong here.

What is the difference between 하고, 이랑/랑, and 와/과 for and?

All three can connect nouns, but they differ in style:

• 하고: very common, neutral, conversational
• 이랑/랑: casual, spoken
• 와/과: a bit more formal or written

So these all work:

• 여권하고 탑승권을
• 여권이랑 탑승권을
• 여권과 탑승권을

For this sentence, 하고 sounds perfectly natural.
