The word 辞职 is formed by combining two characters, each carrying a core meaning that together create a new, specific concept. The first character, 辞, holds the idea of taking leave, declining, or bidding farewell, often in a formal or official context. The second character, 职, means duty, post, or office. When placed together, the compound visually and conceptually depicts the act of "taking leave from one's post", directly representing the action of resigning or quitting a job.
