What languages do they speak in Ecuador? According to Ethnologue there are 24 different languages spoken in Ecuador. For a country a little bigger than Colorado, that's quite a bit. However the official language of the country is Spanish and that's what the majority of the people speak. But It's not uncommon at all to hear news or government information in languages like, Quichua, Shuar, or sign language.
So how quick will we be able to learn the language? Since Karen is from Colombia and Spanish is her first language she obviously has an advantage. There are differences, however, between Colombian and Ecuadorian Spanish but it's mainly vocabulary words and a slightly different accent. You can think of it like the differences between English in the United States and English in Australia. We speak the same languages but depending on how colloquial someone might speak or their accent, you might have some trouble understanding some things.
I started learning/studying Spanish in 2008, so although I wouldn't say I'm fluent and can speak like a native speaker, but I do have a little bit of a head start. I'm thankful for that. I know a lot of missionaries who go to their country of service and get there with very little or no knowledge of the local language. Wow! I'm always impressed by that. How much stress would you have in that situation? How much grace would you need to even pay your rent? I feel so blessed because even if I don't understand what's going on I can always ask Karen and she can explain it to me. Karen thinks that after we're there for a few months my Spanish will get much, much better. For now, I listen, read, and speak Spanish whenever I can.
