⚫︎ The kanji 胤 is a 形声文字 (keisei moji), a phono-semantic compound. ⚫︎ It is composed of two parts: ⚫︎ The left side is 月 (tsuki, getsu), which represents "flesh" or "body". In this case, it is modified to look like the character ⺼which is a variant of 月. ⚫︎ The right side is 延 (en), which conveys the phonetic sound and the meaning of "extend" or "prolong." ⚫︎ Therefore, the character suggests the idea of the "body" being "extended" through offspring, hence "descendant" or "offspring."
