I found a great way to increase my vocabulary of everyday Spanish words: Visit a “dollar” store. We saw one yesterday called a “0,60€” (60 centimos) store. They’re a little behind with the exchange rate!
Finally came across the word for rubber that I was looking for when discussing the gasket on the washing machine with our last host. Saw a pair of rubber gloves at the store: guantes de goma – the word for rubber is “goma”!
I didn’t come to Spain to shop in the dollar stores, but it sure is fascinating!
