nimble, late-going
趙 centers on quick, light movement: being nimble or agile. The sense of 'late-going' is an extension of moving swiftly, perhaps implying a hurried departure or a quick step.
趙 is a phono-semantic compound: 走 (running) suggests movement, while 肖 likely contributes the sound. The exact historical development of the meaning 'nimble' from these components is uncertain.
The running radical 走 encloses 肖, which looks like a small, light figure. Imagine a nimble person sprinting so quickly that they are late-going, always dashing off at the last moment.
For チョウ, picture a nimble chef named Chou who moves swiftly around the kitchen: Chou -> チョウ, and his quick steps match the kanji's meaning.
