The kanji 館 is a phono-semantic compound (形声文字 けいせいもじ) . It is composed of two parts: ⚫︎ The radical 臤 (or part of it) to the left, which signifies firmness, strength or solidity, representing the physical structure of a building. ⚫︎ The phonetic component 官 (meaning "government office," "official"), which contributes to the pronunciation カン. Together, these components suggest a strong, secure, and important place or building.
