Phono-semantic compound (形聲／形声, OC *hmlɯːʔ) : semantic 氵 (“water”) + phonetic 每 (OC *mɯːʔ).

Etymology

Probably related to 晦 (OC *hmɯːs, “dark”); in numerous Zhou texts 海 is described as 晦 (Schuessler, 2007).

Compare the parallelism in Chinese: 溟 (OC *meːŋ, *meːŋʔ, “ocean”) < 冥 (OC *meːŋ, “dark”).

Etymology 1

Kanji in this term
海
うみ Grade: 2
kun'yomi

Alternative spelling
海 (kyūjitai)

⟨umi₁⟩ → */umij/ → /umi/

From Old Japanese, from Proto-Japonic *omi.

Has been thought to have been derived from a compound. There are two leading theories regarding the ultimate derivation:

• Shift from 大 (ō-, “big, great”) + 水 (mi, “water”, combining form). This is problematic phonetically because there is no known term having a related shift from /opo/ → /oː/ → /o/ → /u/, and semantically as there already exists a compound 大水 (ōmizu, “flood”).
• From う (u-, stem indicating “ocean”) + 水 (mi, “water”, combining form). The u- stem is evident in 魚 (uo, “fish”) and 潮 (ushio, “salt water; tide”)

Noun

海(うみ) • (umi) 

1. a sea, an ocean

   海(うみ)の中(なか)にはいろんな生(い)き物(もの)が暮(く)らしています。

   海(うみ)に行(い)こうよ！

   Umi ni ikō yo!

   Let's go to the beach!

   Antonym: 陸 (oka, riku)

2. a lake

   Synonym: 湖 (mizuumi)

3. (figurative) an object covering over a large area, as in 血の海 (chi no umi, “pool of blood”) or 火の海 (hi no umi, “sea of fire”)
4. (planetology) a mare (dark surface of a celestial body, thought to appear like a sea)
5. (calligraphy) in a 硯 (suzuri, “inkstone”), a reservoir where water is stored
