人(ひと、ジン、ニン)

人

Meaning: person

Readings: ひと、ジン、ニン

My hack: It’s a person walking, like those sand drawings they used to have on Sesame Street.

You should also know that when this is a radical it looks like this: 亻  Just rotate the original a bit, or you can imagine it’s a side view of a person bowing slightly.
