• 王孫おうそん — royal descendant

This kanji combines “子” (child) and “系” (lineage or connection), representing a child who continues the family line — a grandchild or descendant. The reading “まご” is used most often in daily life.

孫まごと一緒いっしょに遊あそびました。
I played with my grandchild.

彼かれは 有名ゆうめいな武士ぶしの子孫しそんです。
He is a descendant of a famous samurai.

🎧 “まご” is the most commonly used reading for this kanji in modern Japanese. The on-yomi “ソン” appears in compound words like 子孫.
