Etymology: Derived from the Japanese elements 'aki' (秋) meaning 'autumn' in some contexts but here interpreted as 'bright' or 'spring' depending on kanji, combined with 'na' which can mean 'vegetable', 'greens', or 'what belongs to'. When written with specific kanji like 秋菜, it means 'autumn greens', but phonetically it's often associated with spring due to similar-sounding words and cultural interpretation.
