friend
👥 友人 = 友 (friend) + 人 (person): a friend-person, i.e. a friend
友 already means friend and 人 means person, so 友人 stacks them into a slightly more formal word for friend. The 人 tags it as a human, marking 友人 as a personal acquaintance rather than an abstract friendship.
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.
