Polysemy is the semantic relation among identical words of affiliated or derived meaning. A polyseme can be as simple as a word with multiple similar contexts (mattress pad / paw pad / mouse pad), but they are more interesting and useful when they cross part-of-speech borders. If we say “He will bat the bat with a bat,” bat (swat) and bat (baseball) are polysemes, whereas they are merely homonyms with bat (animal).
