passer-by
🚶 路 (road) + 人 (person) = a person on the road = a passer-by, a stranger
路 means road or path; 人 means person. Put them together and you get someone who just happens to be on the same road as you, with no other connection: a passer-by or stranger.
路 — foot 足 + each 各 (phonetic)
路 is a semantic-phonetic compound. The foot radical 足 on the left signals meaning related to walking or travel, while 各 on the right hints at the ancient pronunciation. Originally referring to a road traveled on foot, it broadened to mean 'road, path, route' in general.
人 — pictograph of a standing person
人 is a pictograph showing a person viewed from the side, with two strokes representing the legs and torso of a standing human. In oracle bone script it clearly depicted a figure leaning slightly forward. The meaning has remained 'person' or 'human' throughout its history.
