Learn Hardcore Korean: jibeseo bumonimgwa iyagihaeyo.

Sure. The sentence consists of:
• 집 (house/home)
• 에서 (location particle “at/from”)
• 부모님 (parents, honorific)
• 과 (particle meaning “and/with” after a consonant-ending noun)
• 이야기 (noun form of “talk/conversation”)
• 해요 (polite present tense of “do”)

What exactly does 에서 indicate in 집에서?

Here, 에서 marks the place where the action happens. So 집에서 means “at home.” Note that 에서 is also used for the starting point of movement, but in this sentence it’s strictly locative.

Why is there no subject like “I” in the sentence?

Korean often omits the subject when it’s clear from context or conversation. Here, the speaker (“I” or “we”) is understood. If you needed to be explicit, you could say 저는 집에서 부모님과 이야기해요.

Why is 과 used after 부모님 instead of 와 or 랑?

• 과 attaches to nouns ending in a consonant.
• 와 is used after vowel-ending nouns.
• 랑 is an informal alternative to 과/와, so you could say 부모님이랑 이야기해요 in casual speech.

What’s the nuance difference between 이야기해요 and 말해요?

• 이야기하다 focuses on having a conversation or exchanging stories.
• 말하다 simply means “to speak” or “to say.”
If you want to emphasize “chatting” or “talking together,” 이야기해요 is more natural.

What level of politeness is 해요?

-해요 is the polite informal style (also called 해요체). You can use it with strangers, coworkers, or people slightly older than you. For more formality, you’d switch to -합니다 (e.g., 이야기합니다).

Can I change the word order, like 부모님과 집에서 이야기해요?

Yes. Korean allows some flexibility with adverbials and phrases:
• 집에서 부모님과 이야기해요
• 부모님과 집에서 이야기해요
Both are grammatically correct and mean the same thing, though native speakers often put the location first.

If I want to specify “talk about homework,” how would I say that?

You insert the topic/object before 이야기해요 with the object particle 를:
• 집에서 부모님과 숙제에 대해 이야기해요
Here 숙제에 대해 이야기해요 means “talk about homework.” You could also say 숙제에 대해 or more colloquially 숙제 이야기를 해요.
