surname
鄧 is a rare kanji used primarily as a surname. Its standalone meaning is simply a family name, with no broader conceptual center.
鄧 is a Chinese surname character. It combines 登 (likely phonetic) with ⻏ (阝, a form of 邑 meaning 'city' or 'place'), suggesting a place name origin. The exact historical development is uncertain.
The left side 登 looks like a person climbing up, and the right side ⻏ is a city wall. Picture a family named Deng who built a famous walled city on a hill.
For トウ, imagine a person named Deng climbing a tall tower (タワー -> トウ) to overlook the city. The tower sound cues トウ while the climbing shape of 登 reinforces the scene.
