kid etymology

It's been fascinating watching Damian begin to/get ready to read. He's much more conscious now of words and how they're formed. He's been trying to suss out rationales. He asked his teacher yesterday if baseball is so called because it has bases, and he told me today that musicians are named that because they play music. Which I liked, because it's a "sh" sound, changed from the "k" sound of the root word. It shows he's really analyzing the words even though he's not seeing them written down.

Of course, he also told me that mushrooms are called that because you mush them in rooms. And he wanted to know if his friend Isaac was named that because he has eyes. And then went on to say, "But everyone has eyes." True.

What I find myself wondering: should I find some etymology dictionary and translate the real Latin/Greek/Germanic/whatever roots of these words? The kid may not know how to add but he'll know the ancient derivation of the word mushroom. Could be interesting.
