About PI
PI is a valid word in the official Scrabble dictionary (US), the UK Scrabble Dictionary and Words with Friends (ENABLE).
Pi is a multipurpose word with several definitions and is pronounced just like the food pie. You may know it best as the ratio of circumference to diameter of a circle, which we usually interpret as approximately 3.14, though the string of numbers can go on forever. It’s considered to be a mathematical constant and is used in many mathematical or physical equations. However, it’s also an irrational number because it’s impossible to know its exact value, making it a fascinating number for mathematicians.
