The kanji 古 is a pictograph. It depicts a mouth (口) and a cross shape (+ or 十) which originally represented a tree or a house. The top part represents a roof of a house or a cover, and the bottom represents a mouth. The meaning evolves to "old" because houses and trees are considered old after a long time. Over time, the form became simplified into its present shape. The character’s composition and its evolution over time highlight the relationship between human experience and the concept of time.
