The kanji 敦 is a 形声文字 (keisei moji), a phono-semantic compound. The left side is 月 (tsuki/getsu), which on its own means "moon" or "month" (though in this context, it has a broader meaning related to "flesh" or "body"). The right side is 享 (kyou), which originally means "to offer" or "to enjoy." Together, they combine the idea of a "thick" or "substantial" body. The meaning evolved to encompass sincerity and harmony. The "月" part here offers a visual aspect, potentially alluding to something solid and substantial, much like a full moon. The phonetic component, "享," provides the sound トン (ton) and hints at the sense of generosity and giving that is related to earnestness.
