🍋🌶️ 酸+甜+苦+辣 = sour + sweet + bitter + spicy — the four flavors of life
A four-character idiom stacking the four basic taste words. Literally the flavors on your tongue; figuratively the full range of life's experiences — the ups, downs, and everything in between.
酸 — wine/jar radical 酉 + 夋 (phonetic)
酸 is a semantic-phonetic compound. The left side 酉 depicts a wine jar and signals meanings related to fermentation and alcohol. The right side 夋 supplies the sound. Originally describing the sour taste of fermented wine, it broadened to mean 'sour' in general and figuratively 'aching' or 'sad'.
甜 — tongue 舌 + sweet 甘
甜 is a compound ideograph combining 舌 (tongue) and 甘 (sweet, itself a pictograph of something held in the mouth). The tongue tasting something sweet conveys the meaning 'sweet' or 'pleasant'. It largely replaced 甘 as the everyday word for sweet taste.
苦 — grass radical 艹 + 古 (old)
Originally referred to a bitter-tasting plant, with the grass radical 艹 indicating its botanical nature and 古 providing the phonetic element. The meaning extended from the literal bitter taste to figurative senses of hardship, suffering, and painful effort.
辣 — 辛 (bitter/pungent) + 束 (bundle)
辣 is a semantic-phonetic compound. The 辛 component carries the meaning, since 辛 originally depicted a tattooing knife and came to mean sharp, bitter, or pungent sensations. The 束 component (a bundle) supplies the sound. Together they describe a sharp, hot, spicy taste.
