Meaning & readings

room, apartment, chamber, greenhouse, cellar

On’yomi シツ
Kun’yomi むろ

Origin

The character 室 combines a roof symbol at the top, which suggests an enclosed space or building, with a sound component at the bottom that hints at how to pronounce it. The roof radical 宀 classifies this as a word about structures or indoor spaces, while the bottom part 至 provides a phonetic clue to the character's pronunciation. Together, these parts create a character that pictures a roofed enclosure—literally a room or chamber. This structure-based approach to writing helped organize thousands of Chinese characters by category while allowing the sound component to guide pronunciation.
