Douglas,
Indeed Opa and Oma are Dutch for grandmother and grandfather. I believe, in German it is the same as well. Dutch and German have a few common words, and some words that are very similar. I lived in the Netherlands for several years.
I also grew up in a bilingual home. Speaking English, Spanish, and some Italian as well. Though the Italian was mostly understood and to be able to answer when needed, by relatives. Never knew what language, or cuisine would be served each night at the dinner table. lol
I must admit though, learning Dutch did take a bit of a toll on my other languages. And even when I moved back to the States, I would be in the grocery store and thinking of items in Dutch. Too funny when I caught myself thinking in Dutch, whilst I am in my home country.
