lobby
🏛️ 厅 = 广 (shelter) + 丁 (ding, phonetic) — a sheltered hall
广 marks a building with a roof; 丁 (dīng) gives the sound, shifted to tīng. The combined character names a large room under that roof — a lobby, hall, or government office department.
厅 — factory radical 厂 + ding 丁
厅 is the simplified form of 廳, originally written with the 广 (building) radical to mean a hall or large room. The simplified version uses 厂 as the semantic component (a shelter or building) plus 丁 as the phonetic, hinting at the sound tīng. It now means hall, lobby, or government office.
