盟 — Alliance, Oath, Pledge

Meaning

The kanji 盟 (めい) primarily means "alliance," "oath," "pledge," or "pact." It represents a solemn agreement or a committed union, often implying deep mutual responsibility and a binding promise between parties. You'll encounter this character in many situations, from formal international relations and historical political agreements to personal, yet equally strong, bonds of friendship and unwavering loyalty.

As an N1 level kanji, 盟 signals its advanced usage and the specific contexts where it appears. It isn't officially assigned to any elementary or junior high school grade in Japan; instead, it's part of the general joyo kanji learned at higher levels of Japanese language study. Mastering 盟 is key to understanding complex Japanese texts and conversations.

The etymological origin of 盟 is particularly fascinating and directly reflects its core meaning. The character is composed of two main components: 血 (ち, ketsu), meaning "blood," at the top, and 皿 (さら, sara), meaning "dish" or "plate," at the bottom. In ancient China, solemn oaths and unbreakable alliances were often sealed with a ritual involving animal sacrifice. The blood from the sacrificed animal would be collected in a dish.

Participants in the oath would typically drink a portion of this blood or smear it on their lips. This powerful, symbolic act represented their shared commitment, mutual responsibility, and the serious consequences of breaking such a sacred pact, as blood was considered sacred and the very essence of life. Thus, the visual combination of "blood in a dish" vividly represents the formation of a sacred covenant or an unbreakable alliance. The meaning of 盟 is deeply connected to this ancient ritual, emphasizing the seriousness and binding nature of profound agreements. The kanji has 13 strokes, giving it a moderately complex yet distinctive appearance.

Readings

The kanji 盟 mostly uses its On'yomi (音読み) readings, which come from ancient Chinese pronunciations. It doesn't have any commonly used Kun'yomi (訓読み), or native Japanese readings, when used alone. Its meaning and usage are almost always expressed when it's part of a compound word.

On'yomi (音読み) — Chinese-derived readings

メイ (mei)

メイ (mei) is the only common On'yomi for 盟, used almost universally in all compound words containing this kanji. It directly conveys the core concepts of alliance, oath, and league, making it an essential reading for advanced Japanese vocabulary, especially in formal, historical, and political discussions.

• 同盟どうめい (dōmei) — This is one of the most common terms, meaning "alliance" or "league." It refers to a formal agreement or union between two or more parties for mutual benefit, protection, or a shared objective. For example, 軍事ぐんじ同盟どうめい (gunji dōmei) means "military alliance," and 経済けいざい同盟どうめい (keizai dōmei) means "economic alliance."
• 盟約めいやく (meiyaku) — Meaning "pact," "covenant," or "oath." This term highlights a solemn, binding promise, often implying a formal and serious commitment between parties. For instance, 不侵略ふしんりゃく盟約めいやく (fushinryaku meiyaku) signifies a "non-aggression pact."
• 盟主めいしゅ (meishu) — This refers to the "leader of an alliance" or a "suzerain." It denotes the dominant or leading figure, nation, or entity within a league or confederation, often holding significant influence or power. For example, 同盟どうめいの盟主めいしゅ (dōmei no meishu) means the "head of the alliance," and a historical figure like Oda Nobunaga might have been seen as a 戦国せんごく時代じだいの盟主めいしゅ (Sengoku jidai no meishu - leader during the Warring States period).

Kun'yomi (訓読み) — Native Japanese readings

The kanji 盟 does not have any common or widely recognized Kun'yomi (訓読み) readings. It is almost exclusively used in compound words with its On'yomi, メイ (mei). Therefore, when you see 盟, expect it to be part of a larger word, pronounced with the メイ (mei) reading, rather than as a standalone native Japanese word.
