"Symonyms"

It is a rainy day here and we are doing some "work" at the table. I was just explaining the difference between "here" and "hear" to Anson. He has flash cards with simple words printed on them and he practices writing them on his paper. We came across the word "here". I said "it's like, 'come here'." And Anson said "or it could be like, 'I hear something'." Pretty good on his part! So I said that hear and here are synonyms. He said, "yea, like M&M's, only different!"
And to top it off he says "symonyms". So cute. I hope he doesn't grow up too fast!
