I had a friend who had a little boy, then about age 8. She and I were "talking babies" and we got on the subject of funny words kids use. Her son, at about age 3, insisted that fire was called "ag-nee". She just about went through the floor when I told her that "Agni" was the Indian (as in India) God of fire. Other than that one fluke, her kid was normal, but it still makes me wonder.
