Ever heard of a homonym? Homonyms are words that sound alike but have different meanings. Sometimes the words are even spelled exactly the same. You wave hello to someone...but you can also watch the ocean waves. OR you can eat a berry, but a smart dog will bury a toy to hide it for later.
Still confused? Here's another example that may help clear things up: Toy Piggy
A toy piggy is a squeaky toy that looks like a piggy. (Oink, squeak, oink)
A toy piggy is also a Shih Tzu who is obsessed with toys and could...perhaps...maybe...just maybe...hoard them.
This, then, is a toy piggy sniffing a toy piggy:
And a toy piggy being attacked by a toy piggy:
And finally, a toy piggy playing with a toy piggy while being rudely covered up with nearby toys (Mom thought that was sooooo funny...but you'll note it didn't break my concentration):
I hope you've enjoyed this English lesson on homonyms (and toy piggies, of course...).
