What is what does poly mean?

The prefix "poly" comes from the Greek word "polus," which means "many" or "much." It is used to create compound words that refer to multiple or many things, such as polyglot (a person who speaks many languages), polygon (a shape with many sides), or polydactyly (having many fingers or toes). In some contexts, "poly" can also refer to a type of relationship or romantic orientation that involves loving or being involved with multiple people at the same time (polyamory).
