Speaking Spanish in Nicaragua

I took Spanish in high school...in the middle-of-nowhere North Dakota. Funny to think about as it was (and still is) the whitest town you'll ever find. How can one practice Span in a setting like that?...you can't... Pretty much learned the super basics and laid the foundation from that. Continued studying in college but the professor was all about the "Spain" Spanish. That time helped me learn more the different speech tenses (past, predicate etc).
Honestly the majority of what I have learned is when I am in Nicaragua, surrounded by Nicaraguans and conversing and hanging out with them. What the dictionary tells you and what the Nicaraguans say on the streets are to different things.
For example: They interchange saber and conocer in many instances. That's not what "school" taught me.

The most important thing is to speak what you know. Practice. Practice, and practice! EVEN AND ESPECIALLY IF YOUR SPANISH SUCKS! Nicaraguans are genuine and kind. They will understand that you're still learning and if you ask, they'll even correct you. If you don't do any of that "because my Spanish isn't good enough" then it won't improve as quickly as you would hope.  Don't be afraid to request mas despacio, por fa
     You can also listen to Spanish music. Something I used to do was watch a movie that I knew in Spanish audio with Spanish subtitles. That helped me a lot to train my ears to pick out words as I listened and read, especially for the people who speak very fast. That is sometimes hard as the subtitles are usually translated word-for-word while the audio is more natural; but I digress. The trick is not to translate literally every word in your brain while trying to keep up as the person keeps talking. You will get headaches if you do that and drain all your energy in the process. In contrast, the trick is to catch the main idea.

Now that I'm married to one, our kids will grow up speaking Span at home and Eng when we go out-and-about so I'll be able to learn the language with them, I imagine.
