+# 용어 사전 (한글 도메인명 ↔ 코드 용어)
+
+> 코드에서 도메인 이름을 임의로 짓지 않기 위한 사전. 백엔드 API 엔드포인트 네이밍과 프론트 코드(라우트 경로, `src/features/` 폴더명, 컴포넌트/타입 접두사 등)가 같은 용어를 쓰게 맞춘다.
+
+## 원칙
+
+- 새 기능/화면을 만들 때 도메인 이름이 필요하면, 영어로 대충 번역하지 말고 **반드시 이 표부터 확인한다.**
+- 여기 없는 새 도메인이 생기면 백엔드와 협의해서 엔드포인트 네이밍을 먼저 정하고, 그걸 이 표에 추가한 뒤 코드에 반영한다 — 프론트에서 먼저 임의로 정하지 않는다.
+- 표의 "코드 용어"는 백엔드 엔드포인트 세그먼트(`/api/{코드 용어}/...`)와 동일한 문자열이다. 프론트에서는 아래 "적용 범위"에 그대로 쓴다.
+
+## 사전
+
+| 한글 도메인명 | 코드 용어 |
+| --- | --- |
+| 공통 | `auth` |
+| 사용자 | `users` |
+| 게시판(공지) | `notices` |
+| 게시판(열린피드백) | `feedbacks` |
+| 빌릴게 | `bililge` |
+| 사물함 | `lockers` |
+| 슬랑제 | `seulrangjes` |
+| 아카이빙 | `archives` |
+| 챗봇 | `chat` |
+| 파일 | `files` |
+| 행사(event) | `events` |
+| 회비 납부 | `fee` |
+
+## 적용 범위
+
+- 백엔드 API 엔드포인트 경로: `/api/{코드 용어}/...`
+- 프론트 라우트 경로: `/{코드 용어}`
+- `src/features/{코드 용어}/` 폴더명
+- 그 안의 컴포넌트/타입/상수 이름의 도메인 접두사 — 코드 용어를 PascalCase로 바꿔서 쓴다 (예: `bililge` → `Bililge...`, `bililgeItems` 같은 camelCase 변수명도 동일)
+- Figma 노드/화면 이름은 그대로 한글을 쓴다(디자이너와의 소통 채널이라 번역하지 않음) — 코드 파일 최상단의 `// Figma: ...` 주석에서만 한글 화면명을 남긴다.
+
+## 반영 사례
+
+- "빌릴게" 기능: 처음엔 `rental`로 임의 명명했다가, 이 사전을 도입하면서 `src/features/rental/` → `src/features/bililge/`로 전체 리네이밍했다(#18).
