Root Explanation

Antenna → The word 'antenna' comes from Latin 'antenna', meaning a sail yard or a yardarm, which refers to the long, projecting part of a ship's sail. The term evolved to describe the sensory appendages of insects and later to refer to devices that receive or transmit signals, drawing a parallel to the way sails catch the wind.

Memory Tip

Think of 'antenna' as a 'sail' that catches signals instead of wind, helping you remember that it refers to a device that receives or transmits information.
