large, clear, remarkable
倬 centers on standing out as notably large, clear, or remarkable, like a person whose presence is unmistakable.
倬 combines 亻 (person) with 卓, which likely contributes both sound and the idea of prominence or excellence, suggesting a person who is outstanding.
A person 亻 beside 卓 (a table or prominent object) stands out as large and remarkable, like someone towering over a table.
For タク, imagine a remarkable person giving a talk at a table: talk -> タク, and their clear, large presence captivates everyone.
