Kanji for Water (水), Swim (泳), Sea (海) & Ocean (洋): Mastering the Water Radical (氵)
'What is the kanji for water?' is one of the top 3 most-searched kanji questions online. Once you know 水 (Water) and its 3-droplet splash radical (氵), you immediately unlock 泳 (Swim), 海 (Sea), 洋 (Ocean), 活 (Lively), and 注 (Pour).
"What is the kanji for water?" is one of the top 3 most-searched kanji questions on the entire internet. The answer is 水 (みず mizu / すい sui). Even better, when 水 moves to the left side of a compound kanji, it compresses into three water droplets (氵 — sanzui), unlocking an entire aquatic family!
1. 水 (Water — みず / すい) & 泳 (Swim — およ / えい): Missouri Water & Yo-Yo Swimmers
Inspect the flashcards for 水 (Water) and 泳 (Swim) below:
- 水 (Water — みず mizu / すい sui): Bottle of Missou-ri (みず mizu) free water that looks super i-nteresting (すい sui)! Use みず (mizu) when ordering a glass of water by itself, and すい (sui) in compounds like 水曜日 (suiyōbi — Wednesday).
- 泳 (Swim — およ(ぐ) oyogu / えい ei): Adds the 3-droplet water splash (氵) on the left! Eighteen (えい ei) year olds apparently really love playing with a yo-yo (およ oyo, as in 泳ぐ oyogu) and swimming! Put 水 (すい) + 泳 (えい) together and you get 水泳 (すいえい suiei — swimming).
2. 海 (Sea — うみ / かい) vs. 洋 (Ocean / Western Style — よう): Kayak Humidity vs. Yogurt Sheep
Learners constantly mix up 海 (Sea) and 洋 (Ocean / Western Style) because both start with the 3-droplet water splash (氵). Look at what sits on the right side of each card:
- 海 (Sea — うみ umi / かい kai): Water (氵) + Every (毎). Humidity (うみ umi) is crazy high — the ideal day for a kayak (かい kai, as in 海外 kaigai 'overseas') adventure out on the sea!
- 洋 (Western Style / Ocean — よう yō): Water (氵) + Sheep (羊). So the kanji for western style / ocean is just a sheep eating yogurt (よう yō, as in 洋服 yōfuku 'Western clothes' and 太平洋 Taiheiyō 'Pacific Ocean') behind big ocean waves!
3. Two More 氵 (Water Splash) Favorites: 活 (Lively — かつ) & 注 (Pour — ちゅう / つ)
Whenever you spot those three water droplets (氵) on the left, look for the splash in the scene:
- 活 (Lively — かつ katsu / い i): Water (氵) + Tongue (舌) → Just a lively cat-su (かつ katsu, as in 生活 seikatsu 'daily life') in a sombrero smiling from ear (い i) to ear!
- 注 (Pour — ちゅう chū / つ tsu): Water (氵) + Master (主) → If a temple is on fire, you must choose (ちゅう chū, as in 注文 chūmon 'order' and 注意 chūi 'caution') to pour a tsunami (つ tsu) of water on it!
