Wii Remote vs. Nunchuk: Name Origins & Function

The Wii Remote (Wiimote) and Nunchuk are two separate controllers that connect via a short cable. They are not the same device.

Wii Remote (Primary Controller)

Form: TV-remote shape, held in dominant hand.
Sensors: IR camera (tracks Sensor Bar), 3-axis accelerometer, speaker, rumble.
Inputs: A, B (trigger), 1, 2, +, -, Home, Power, D-Pad.
Expansion Port: Bottom connector for Nunchuk, Classic Controller, MotionPlus, Wii Wheel, etc.

Nunchuk (Secondary Controller)

Name Origin: Named after the Okinawan nunchaku (two sticks linked by rope/chain). The cable tether and off-hand usage mirror the weapon's form.
Form: Ergonomic grip for non-dominant hand.
Inputs: Analog stick (movement), C (trigger), Z (shoulder).
Sensors: 3-axis accelerometer (no IR camera).
Power: Passive—draws power from Wii Remote.

MotionPlus (2009)

Added gyroscope to Wii Remote (built into Wii Remote Plus), enabling true 1:1 motion (Wii Sports Resort, Skyward Sword). Nunchuk never got gyro; later games used dual Wii Remotes for 1:1 off-hand.

Summary: Wii Remote = pointer/main actions. Nunchuk = movement/off-hand mods. The name "Nunchuk" is a direct reference to the chained martial-arts weapon.
