wholly, solely, entirely, lovey, cute, gather, collect, put in order
This rare kanji has no clear standalone meaning. Its given glosses are scattered: some point to exclusivity or wholeness, others to affection or cuteness, and still others to gathering or arranging. Treat its meaning as uncertain.
嫥 combines 女 (woman) with 專, which likely contributes the sound. The exact historical development is uncertain, and the modern form does not clearly explain the scattered meanings.
A woman 女 beside a focused, spindle-like shape 專: imagine her wholly devoted to gathering cute things and putting them in order.
For セン, picture a woman collecting a hundred (百, ひゃく) cute items, but she only needs one sen (千, せん) to feel wholly satisfied: sen -> セン.
