左手

左 (zuǒ) means 'left,' and 手 (shǒu) means 'hand.' Together, 左手 refers to the left hand, the hand that is not dominant for most people.

The character 左 is derived from the shape of a person's left side, while 手 is a pictograph of a hand. Combining them clearly indicates the left hand, distinguishing it from 右手 (yòu shǒu), meaning 'right hand.'

Left hand is commonly used in daily life, such as when describing body parts, giving directions, or discussing handedness. In some contexts, it may also carry cultural or symbolic meanings, though it is primarily a literal term.
