The kanji 瑞 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is 礻 (示) which is the radical for "spirit," "god," or "offering." The right side is 耑 (tuan), which originally meant "beginning" or "new start." Therefore, 瑞 originally indicated a good sign from the gods or a favorable beginning, hence its meaning of "auspicious." The character evolved over time, but the core meaning of good fortune and favorable signs has remained.
