IPA: /kənˈtræpʃən/
KK: /kənˈtræpʃən/
A mechanical device or gadget that is often complicated or unusual in design.
He built a strange contraption to help him with his gardening.
Contraption is formed from "con-" (meaning together) and "trap" (from the Middle English "trappe", meaning to catch or ensnare). The word refers to a device or gadget that is put together, often in a clever or unusual way, to catch or perform a specific function.
Think of a device that is cleverly 'put together' ('con-') to 'catch' or perform a task ('trap'). This helps you remember that a contraption is a unique or inventive device.
