      "body": "Welcome! I’m your reading tutor for the very first lesson in Korean, unit 1.1 자음과 모음 (Consonants & vowels).  \nThis unit is all about **how a block is built**: one initial consonant + one vowel. The blocks you will read are the simplest syllables in Korean – no final consonants, no compound vowels, no tense or aspirated sounds.  \n\n### Why this rule matters  \nEvery Korean word is made of these blocks stacked together. If you can read a block, you already know how to decode every other block that follows it. The first step is therefore the most fundamental: recognizing and saying the consonant‑vowel pair.  \nThe ten basic vowels are ㅏ ㅑ ㅓ ㅕ ㅗ ㅛ ㅜ ㅠ ㅡ ㅣ.  \nThe plain consonants you will see in this unit are ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅅ ㅇ ㅈ ㅎ.  \n\n### A quick example of a block  \nTake **나**: it is made of the consonant ㄴ and the vowel ㅏ, written together as 하나의 블록.  \nWhen you see this block, you read “na”.  \nThe same idea applies to every other block:  \n- **너** (ㄴ+ㅓ) → “neo”  \n- **이** (ㅇ+ㅣ) → “i” (the ㅇ is silent at the start)  \n- **그** (ㄱ+ㅡ) → “geu”  \n- **저** (ㅈ+ㅓ) → “jeo”\n\n### Common mistake  \nA new learner often mixes up ㄴ and ㄹ because they look similar. If you read a block that starts with ㄴ but sound it like ㄹ, the meaning will be wrong. Practice the shapes and sounds of each consonant separately.\n\n### New words for this unit  \nThe words we’ll use in your exercises are all simple blocks that fit the rule: **나 너 이 그 저**.  \n\nYou’re ready to start reading! Let’s practice by writing these words from English prompts.\n\n---\n\n::task recall\nI | 나\nyou (casual) | 너\ntwo (Sino) | 이\nthat (near you) | 그\nI (humble) | 저\n\n::words\n나 | I | ㄴ+ㅏ\n너 | you (casual) | ㄴ+ㅓ\n이 | two (Sino) | ㅇ+ㅣ\n그 | that (near you) | ㄱ+ㅡ\n저 | I (humble) | ㅈ+ㅓ"
