Understanding Informal Korean Speech: "해체" (Casual Speech Level)

Korean has various speech levels depending on formality, politeness, and social hierarchy. Among these levels, 해체 (Haeche) is one of the most casual forms, often used between close friends, family members of similar age, or younger people. It's characterized by the lack of honorifics and simpler verb endings. 반말로 불리며 친밀한 사이에서 사용. 나이가 같거나 어린 사람들 사이, 또는 매우 친한 관계에서 사용. 격식이 없고 캐주얼함.
Characteristics of 해체:

1. Direct and Informal: It is straightforward and doesn’t include polite markers like 요 or honorific forms.
2. Common Endings:
   • Present Tense: Ends with 다, 아/어, or simply the verb stem.
     • Example: 먹다 → 먹어 (eat)
   • Past Tense: Uses 었/았/였.
     • Example: 가다 → 갔어 (went)
   • Future Tense: Uses -(으)ㄹ 거야.
     • Example: 갈 거야 (will go)
3. Dropped Subjects: Since Korean is a context-heavy language, the subject is often omitted, especially in 해체.

When to Use 해체:

• Between close friends of similar age.
• With younger family members.
• In casual text messages or online conversations.
• Avoid in formal settings, with strangers, or with people of higher social status.
