Origin

This character combines a grass radical at the top, which classifies it as a plant-related word, with the component (old) at the bottom that serves as a sound hint for pronunciation. The character likely originated from a bitter plant or herb, since bitterness became the core meaning. From "bitter" as a physical taste sensation, the meaning expanded to "suffering" and "hardship" as abstract forms of unpleasantness. The grass element makes sense because many bitter medicinal plants would have been familiar to ancient Chinese speakers encountering this word.
