Tips
history
彳 is the left half of an intersection - paired with 亍 (the right half) to write 彳亍, a literary term for ambling slowly. As a radical it nearly always sits on the left of a character, which is why teachers nickname it 双人旁 (two-person side).
usage
彳 marks motion and roads: 行 (walk/row), 往 (go toward), 很 (very, originally 'follow'), 得 (obtain), 律 (law), 微 (minute/subtle), 街 (street). Spotting it tells you the character likely involves traveling or paths.
Radical
StepKangxi #60
Stylized image of a left-side crossroads, with 亍 mirroring it on the right. As a Kangxi radical 彳 indexes characters relating to walking, roads, and human conduct - 行, 往, 律, 得, 徒, 街, 徽. Highly productive on the left edge of compounds; nearly always semantic rather than phonetic.
