5. History
Liushu category: Phono-semantic (形声)
Origin: Originally, the character combined 矢 (arrow) and 口 (mouth). In ancient times, an arrow flying swiftly and accurately represented the sharpness of intellect, and the mouth represented articulating that truth.
Semantic Evolution: From the rapid strike of an arrow of thought, it broadened to mean possessing awareness, understanding, and knowing facts.
In classical Chinese, 'zhī' also frequently doubled as a grammatical possessive particle, equivalent to 的 (de).
