Questions & Answers about chaegeul gabang ane neoheoyo.

What is the role of 을 in 책을?

을 is the direct‐object marker. It attaches to a noun ending in a consonant (here 책) to show that this noun is what the verb acts upon.

Why is it 가방 안에 instead of just 가방에?

• 안 means “inside.”
• 에 is the locative particle meaning “at/in.”
  Together, 안에 specifies “inside” something. While 책을 가방에 넣어요 can also mean “put the book in the bag,” saying 가방 안에 explicitly highlights that it goes into the interior of the bag.

Why is there no subject marked in the sentence?

Korean often omits the subject when it’s clear from context. Here, the implied subject is “I” (or whoever is performing the action). In a conversation, you’d already know who’s doing the putting, so you don’t need to state it.

What politeness level is expressed by 넣어요?

The -어요 ending is the polite, informal style (해요체). It’s friendly but respectful.

• More formal: 넣습니다 (하십시오체)
• More casual: 넣어 (해체)
