But **Korean works fundamentally differently**: `이\u002F가` doesn't just mark the subject—it *highlights* what is **new, specific, or the focus of the sentence**. This is a key mindset shift.\n\nIn English, you say *\"A cat is sleeping\"* and the subject is inherently the main idea. In Korean, `고양이가 자고 있어요` can mean the same thing, BUT the particle `가` is actually saying: **\"It is the cat (specifically, not something else) that is sleeping.\"** The focus is on **what is doing the action**, not just stating a fact.\n\nHere's the crucial difference: English uses **word order** and **context** to convey focus. Korean uses **particles**. When you use `이\u002F가`, you're emphasizing or introducing that noun as the **specific answer to an implied question** like \"What is...?\" or \"Who is...?\" In contrast, `을\u002F를` (object marker) and `은\u002F는` (topic marker) convey different information relationships. The `이\u002F가` particle is **restrictive and specific**—it narrows down possibilities rather than just labeling a general topic.\n\nThink of it this way: **`이\u002F가` asks \"Which one?\"** while **`은\u002F는` asks \"As for the topic...\"** English doesn't really distinguish these grammatically, so learners must actively rewire their thinking to **see subjects as either newly introduced or specifically highlighted** versus **topics being discussed**.",[],[17,23,29,35,41,47],{"en":18,"ko":19,"ko_audio":20,"audio":21,"audios":22},"누가 왔어요? 친구가 왔어요.","Who came?
