The kanji 盟盟 is a 会意文字 (かいいもじ), a compound ideogram, formed by combining two elements: 皿 (dish or plate) and 皿 (same meaning) and 月 (moon). The combination of dishes, and the moon initially represented an oath taken, likely with blood being mixed and shared in a dish as a symbolic gesture of unity and commitment, observed under the light of the moon. The original meaning evolved to represent the concept of a covenant or alliance. The moon, with its consistent cycles, also symbolized the enduring nature of the agreement. Over time, the form simplified.
