A couple of weeks ago I kept a handful of spanish-speaking children entertained by talking to them in spanish (where I live currently has very few bilingual anglos) but they kept asking me a question and I didn't know the word they were using. I gathered from their explanations that they were asking me about my heritage, but they were 4-6 and couldn't really communicate the meaning in english. The phrase sounded like "¿aronde eres?" but my googling is turning up zilch.
Does this sound similar to any phrase you know? It almost sounded to me like the "r" was subbing for a different sound, maybe a region-specific switch?
