The Water Splash Radical (氵 — Sanzui): 水 (Water), 泳 (Swim), 注 (Pour / Caution) & 活 (Lively 生活)
When 水 (Water) moves to the left side of a kanji, it turns into three splashing water droplets: 氵 (sanzui). See how those three drops power 泳 (Swim), 注 (Pour / Attention), and 活 (Lively / Daily Life 生活)!
Ever wondered why 生活 (seikatsu — daily life / living) uses the Water radical in 活 (katsu)? Look at the right side of 活: it is 舌 (shita — Tongue)! A parched tongue revived by splashing water (氵) is the ancient symbol of vitality and active life!
