he, him, other

他 is composed of 人 (person) and 也 (snake, also). 也 is a pictograph of a snake, sharing the same origin as 它. Snakes, lacking limbs, are less familiar to humans compared to other creatures, so a character derived from the snake’s form is used as a third-person pronoun. Since 它 represents non-human creatures or inanimate objects, 他 is used to denote a third-person human pronoun.
