徘徊
páihuái · HSK 7
to pace back and forth; to dither; to hesitate
🚶 both chars carry the 彳 step radical; 徊 hides 回 return, so you step back and forth
徘徊 is a bound two-syllable word where neither half stands alone. The shared 彳 (step) radical marks walking, and the 回 (return) inside 徊 captures the back-and-forth pacing and wavering that the word names.
