classroom
🏫 教室 = 教 (teach) + 室 (room) — a room for teaching
教 means teach or instruct; 室 means room or chamber. Together they form the literal compound 'teach-room' = classroom. Compare 卧室 (sleep-room = bedroom) and 浴室 (bath-room) for the same 室 pattern.
教 — 老 (filial son being taught) + 攵 (hand with stick)
教 originally depicted an adult holding a stick or rod (攵) instructing a child, often shown with the element 爻 (lessons/counting) above 子 (child). It is a classic associative compound meaning 'to teach' or 'to instruct,' with the right side suggesting discipline and guidance. The modern meanings 'teach, religion, doctrine' all extend from this image of formal instruction.
室 — roof 宀 + arrive 至
A semantic compound: 宀 (roof/house) over 至 (to arrive). The image is a place one arrives at and stays in — an inner room. From 'inner chamber' the meaning broadened to 'room' generally, and by extension to specialized rooms like an office or laboratory.
