5. History
Liushu category: Pictogram (象形)
Origin: In Oracle Bone script, 大 was drawn as the silhouette of a grown human being facing forward, with arms and legs spread out to emphasize large physical stature compared to a child.
Semantic Evolution: From the literal image of a full-grown person, it naturally expanded to mean 'big', 'great', 'eldest', and 'to a great extent'.
It is one of the foundational building blocks of the Chinese writing system.
Adding a dot to 大 creates 太 (very/too), and adding a roof over it creates 天 (heaven/sky).
