引 — bow 弓 + vertical stroke 丨
A compound ideograph showing a bow 弓 with a vertical line 丨 representing the drawn bowstring. The original meaning was 'to draw a bow,' which extended to 'pull,' 'lead,' 'guide,' and 'cite.' The vertical stroke depicts the action of pulling the string back.
下 — horizontal line 一 + mark below
下 is an indicative character: a long horizontal line represents a reference level, and a shorter stroke placed beneath it points to the area below. The original meaning 'below, down' comes directly from this spatial diagram, and it later extended to verbs like 'descend' and 'lower'.
