sturdy, brawny, bold
逞 centers on robust physical strength and boldness: being sturdy, brawny, and daring enough to act forcefully.
逞 combines 辶 (movement) with 呈, which likely contributes the sound and the idea of presenting or displaying. The overall sense is moving forward with bold, sturdy vigor.
The movement radical 辶 wraps around 呈, like a bold, brawny person striding forward and showing off their sturdy build.
For テイ, imagine a sturdy table (テーブル, tēburu) being carried boldly: the 'tei' in table cues テイ, and the brawny mover strides forward with it.
