Questions & Answers about jeoneun chinguege jeonhwahaeyo.

Why is 에게 used after 친구? Can I use a different particle?

에게 marks the indirect object or recipient of an action—in this case, the person you’re calling. You cannot use -을/를 here because 친구 isn’t the direct object of “call” (the direct object is the act of calling, 전화).
Alternatives:

• Colloquially you can say 친구한테 전화해요 (한테 = informal equivalent of 에게).
• To show extra respect, for someone above you socially, you could use the honorific dative 께, e.g. 선생님께 전화해요.

Why isn’t there a direct object marker (like -를) on 친구?

Because 친구 is not a direct object but the receiver of the phone call. The basic verb is 전화하다 (“to make a phone call”), so if you wanted to treat 전화 as a noun, you could say 전화를 해요 (placing -를 on 전화), but you still wouldn’t attach -를 to 친구.

What’s the difference between 저는 and 제가 in this sentence?

• 저는 uses the topic marker -는, framing “I” as the topic of conversation.
• 제가 uses the subject marker -가, placing slight emphasis on “I” as the doer.
  In everyday polite speech, 저는 친구에게 전화해요 is most common. 제가 would sound more emphatic or used in a contrastive context.
