Core Grammar Rule: -(으)ㄹ래요 vs. -(으)ㄹ게요
These two endings are used in informal situations to talk about intentions and suggestions, but they have different functions.
Meaning & Usage
-(으)ㄹ래요: This ending has two main uses.
Asking Intention/Preference: Used to ask the listener what they want to do. It's a soft, friendly suggestion. (e.g., 커피 마실래요? - Do you want to drink coffee?)
Stating Speaker's Intention: Used to state your own decision or what you are going to do. (e.g., 저는 커피 마실래요. - I'll have coffee.)
-(으)ㄹ게요: This ending is used only to state the speaker's intention or to make a promise to the listener. It often implies the speaker's action is in consideration of the listener or the situation. You cannot use it to ask a question about the listener's intention. (e.g., 제가 커피를 탈게요. - I'll make the coffee.)

Native Nuance & Mistakes
Understanding the speaker-listener dynamic is key to using these endings correctly and avoiding common errors.
Don't Ask Questions with -(으)ㄹ게요
Context: A very common mistake for learners is trying to ask a question with -(으)ㄹ게요. This ending is only for stating the speaker's (my) intention. It sounds like you are making a promise or a decision. Asking "제가 문을 닫을게요?" is unnatural. To ask for permission or opinion, use -(으)ㄹ까요?.
Example: Do: 제가 문을 닫을까요? (Shall I close the door?) (O) / Don't: 제가 문을 닫을게요? (Am I going to close the door?) (X)
-(으)ㄹ래요 vs. -고 싶어요
Context: Both can express desire, but -(으)ㄹ래요 often implies an immediate action or a suggestion to do something together. -고 싶어요 is a more general statement of desire or hope. When ordering food, -(으)ㄹ래요 (I'll have...) is more natural than -고 싶어요 (I want to have...).
